		  batch and pnd (or calculation thereof) that do.

	  - Fixed calculation of abs lookup table

	  - Removed some superfluous settings (commented out for now)

	* PyARTS/arts_scat.py: Shrinked
	  - Removed bug-causing import statement

	* TODO.txt: Expanded
	  - Binary ARTS files? But in any case Daniels work.

2011-04-08	Gerrit Holl	<gerrit.holl@ltu.se>

	* PyARTS-1-1-41

	* test/arts_scattest.py: Bugfix
	  - Direct passing of a string to the constructor of
	    SingleScatteringData is no longer supported; use
	    SingleScatteringData.load(...) instead.
	
	* PyARTS/arts_types.py: Bugfixes
	  - Use XMLfile-class to write XML, so that header and footer are
	    properly written and the XML-file becomes well-formed.
	  - Fix typo, p_type -> ptype
	  - Don't forget to return the object in the method-turned-classmethod
	    SingleScatteringData._load_from_artsXML_object.
	 
	* PyARTS/arts_scat.py: Bugfixes
	  - Forgot to import c
	  - Don't try to write non-existing description
	  - aspect_ratio is passed on, not inferred
	  - fixed typo, nt -> nT
	  - fixed reshaping; .reshape(...) does not change the object
	    in-place, whereas spam.shape = (a, b, c) does.

2011-04-07	Gerrit Holl	<gerrit.holl@ltu.se>

	* PyARTS-1-1-40

	* PyARTS/arts_types.py: Expanded, behaviour changes
	  - Move SingleScatteringData here, but without the calculations
	    wARNING: untested, so I'll probably fix this soon
	  - DROPPED SUPPORT for direct passing of string to
	    SingleScatteringData; use classmethod .load(...) instead.
	  - Add class for ScatteringMetaData
	  - Add class for ArrayOfSingleScatteringData; this also contains
	    ArrayOfScatteringMetaData. This class has two methods to read from
	    Hong or Yang data, respectively.
	  - Move saving functionality to ArtsType baseclass
	  - New class ArrayOf, generic container; thus grossly simplified
	    ArrayOfGriddedField3

	  - Fixed bug in atmospheric reading
	  - Removed wrong automated selection of frequencies to read from
	  catalogue, user should indicate this instead

	  - Set geoid

2011-03-11	Gerrit Holl	<gerrit.holl@ltu.se>

	* PyARTS-1-1-34

	* PyARTS/arts.py: Behaviour changes
	  - Got rid of arts_..._var_... dictionaries, do this in
	  arts_file_types instead (so stuff is centralised)
	  - Don't call the shell to remove files. Dangerous (e.g. what is
	  filename end in a / due to some bug?)
	  - Removed ArtsRunCollection class; no need to run multiple ARTS at
	  the same time.
	  - Some layout/spelling changes.

2011-03-10	Gerrit Holl	<gerrit.holl@ltu.se>

	* PyARTS-1-1-33

	* TODO.txt: Removed svn:executable property

	* PyARTS/arts.py: Behaviour changes
	  - Got rid of defaults mapping, this is accurately done by including
	  general.arts.
	  - Got rid of template file, no longer needed.
	  - Fixed some docstrings.

	* PyARTS/arts_file_components.py: Behaviour changes
	  - Get rid of defaults mapping
	  - Simplified VectorSet implementation

	  - Do some checks in ArtsCodeGenerator.__init__
	  - Add date to header
	  - Comment out or remove stuff I now think to be redundant. Now it
	  not only works, I also understand what I'm doing, at least for the
	  clear-sky pencil-beam monochromatic case.

2011-03-08	Gerrit Holl	<gerrit.holl@ltu.se>

	* PyARTS-1-1-32

	* PyARTS/arts.py: Implementation changes
	  - Replace os.popen* by subprocess.Popen (preferred method)

	  - Added note on multiprocessing

2011-03-07	Gerrit Holl	<gerrit.holl@ltu.se>

	* PyARTS-1-1-31

	* PyARTS/clouds.py: Small changes
	  - Created a __repr__ method for the cloud (will expand later) to
	  provide some useful information on interactive use.

	* PyARTS/__init__.py: Documentation changes
	  - Adapted docstring to new behaviour. Runs fine in doctest except
	  for the last cases. Monte Carlo simulations still have different
	  results, even though the seed is the same?!
	
	* PyARTS/arts.py: Small changes
	  - Fixed bugs introduced by getting rid of "from x import *"
	  - More information in exception messages
	  - Added __repr__ method to ArtsRun objects (will provide more info
	  later)

	* PyARTS/arts_file_components.py: Significant changes
	  - Added significant amounts of documentation (runs in doctest)\
	  - Added a commenter-decorator around all ArtsCodeGenerator methods
	  generating code, to ease debugging of automatically generated arts
	  control-files.
	  - Prevent ArtsCode objects from being instantiated
	  - Write spaces rather than tabs (to be honest, to shut up
	  doctest...)
	  - Added toString method to ArtsCodeGenerator class
	  - grids want nelem, not n
	  - Set default interpolation order to 1. 
	  - Changed behaviour of Comment objects
	  - Resorted MC stuff lost in wrong method
	  - Added clearsky-sim-commands (ycalc & friends; what about this
	  ycalc agenda?)
	
	* PyARTS/arts_scat.py: Minor changes
	  - Made ArrayOfSingleScatteringData an object
	  - don't raise RuntimeError, raise PyARTSError instead
	  - use 21st century Python code (no more .has_key(...))

	* examples/mc_incoming_gen.py: Minor change
	  - Have pressure-grid up to 101300 rather than 107000 to shut up ARTS
	  complaining about too far extrapolation
	
	* examples/MCwith3Dboxcloud.py: Minor change
	  - Have pressure grid up to 101300 rather than 100000 to shut up ARTS
	  complaining about too little interpolation (?)
	
	* ChangeLog: Documented my changes


2011-03-04	Gerrit Holl	<gerrit.holl@ltu.se>

	* PyARTS-1-1-39

	* Generally:
	  Upgrading to ARTS-2 syntax. Refactoring. Work in progress.
	  Still incomplete. Will continue after the weekend.
	  Remaining errors appear to be hard to solve, e.g.
	  [arts]/src/matpackI.h:314: Numeric ConstVectorView::operator[](Index) const: Assertion `n<mrange.mextent' failed.
	  Status: FAILED (failures=1, errors=1) (not bad IMHO)
	
	* PyARTS/arts_file_components.py: Rewritten
	  - Largest changes in this function
	  - Update syntax to ARTS-2
	  - Get rid of all the function working on a "arts settings
	  dictionary" and create a class to group those instead. The arts
	  settings are now kept within the state of the object. The settings
	  are passed on when constructing the object and then all the methods
	  take no arguments at all. Several alternate constructors exist,
	  those are classmethods. I have not yet written a lot of
	  documentation, so read the source code for details.
	  - Rewrite WSM for new syntax.
	    BREAKING BACKWARD-COMPATIBILITY
	  - Rewrite AgendaSet for new syntax.
	  - Add new classes Include and Comment
	  - All those classes inherit from ArtsCode
	  - Grossly simplified IndexSet, VectorSet etc.
	    BREAKING BACKWARD-COMPATIBILITY
	  - removed arts_batch_from_template as I don't know how to do this,
	  and it should be redundant soon
	  - Get rid of "from x import *"

	* PyARTS/arts_types.py: Adapted
	  - Get rid of "from x import *" notation

	* PyARTS/arts_scat.py: Adapted
	  - Get rid of "from x import *"

	* PyARTS/__init__.py: Adapted
	  - Remove arts1

	* PyARTS/arts.py: Adapted
	  - raise exception if Arts returns error code
	  - Get rid of "from x import *"
	  - Adapt to OO-ized arts_file_components
	  - Make ArtsRun an object

	* PyARTS/general.py: Adapted
	  - Stop pickling, it's not working.
	
	* test/arts_scattest.py: Adapted
	  - Get rid of from x import *
	  - Fix some strange argmax() usage

	* TODO.txt: Adapted
	  - Finish this transition
	  - Expand the cloud class
	  - Other cleanup

	* ChangeLog: Adapted
	  - Added changelog entry for large change.

2011-03-01	Gerrit Holl	<gerrit.holl@ltu.se>

	* PyARTS-1-1-38

	* PyARTS/clouds.py: Adapted
	  - Fix typo in docstring
	  - Make Cloud an object and use "is not None" rather than testing for
	  equality (testing for equality against None is dangerous, because
	  objects can override the equals-operator)

	* PyARTS/arts_types.py: Adapted
	  - Make GriddedField3 an object

	* PyARTS/__init__.py: Adapted
	  - Fix some errors in documentation. saveTensor should be save,
	  gas_species should be abs_species and gas_abs_lookup should be
	  abs_lookup.
	
	* PyARTS/arts.py, PyARTS/general.py: Adapted
	  - Replace Float by 'float32' as is standard in newer numpy versions
	
	* PyARTS/arts_file_components.py: Adapted
	  - montecarlo_sim_commands = mcgeneral_sim_commands? There are
	  several calls to the former, but only mcgeneral_sim_commands and
	  mcipa_sim_commands are defined.

	* examples/raindrops_clouddrops_crystals.py: Adapted
	  - Added 'special' to explicitly imported modules

2011-02-25	Gerrit Holl	<gerrit.holl@ltu.se>

	* PyARTS-1-1-37

	* PyARTS/{clouds,arts_types,arts,arts_file_components,general,arts_math,arts_scat}.py:
	  - Use more specific exceptions. All PyARTS-specific exceptions now
	    derive from PyARTSError, which in turn derives from Exception.

2011-02-24	Gerrit Holl	<gerrit.holl@ltu.se>

	* PyARTS-1-1-36

	* PyARTS/physics.py: Adapted
	  - Added units to constants (in comments)
	  - Added function to convert wavelength to frequency

	* PyARTS/arts_scat.py: Adapted
	  - SingleScatteringData is now a new-style class
	  - If NP=None, particles are not spheroids (and calc(...)) will throw
	    an exception. This is to enable the use of this class for more
		generic ice particles.
	  - Make it possible to use keyword arguments
	  - Only use the default description if no description is passed.

	* README.txt: Adapted
	  - Rewritten this a bit. Now needs Python 2.6 (released October
	    2008).
	  - Removed notice on uptodate source distribution at Cory Davis'
	    website, because this is not factually correct.
	  - Some other small changes here.

2010-12-23  Cory Davis  <cory.davis@metservice.com>

	* PyARTS-1-1-35

	* removed laheybuild.sh on the assumption that nobody uses it.

2010-10-29	Gerrit Holl	<gerrit.holl@ltu.se>

	* PyARTS-1-1-34

	* (generic comments): (–: hope nobody minds my boldness here :–)
	  - In any file I edited, I changed the indentation style from a mixture
	    of tabs and spaces to spaces only. Mixing tabs and spaces is a bad
		idea because different people have different tabstops. Indenting with
		four spaces follows PEP-0008 @ http://www.python.org/dev/peps/pep-0008/
	  - I changed string exceptions to class exceptions. Class exceptions have
		been the preferred method ever since 1997 and string exceptions have
		been deprecated for a long time, and were finally removed in Python
		2.6. This affects
		PyARTS/{arts_file_components,arts_math,arts,arts_scat,arts_types,coulds,general}.py
	  - Only 2 errors in the unittest remain and both are due to "arts1 not
		supported".

	* test/cloudstest.py: Adapted
	  - Added "from scipy import integrate", this is apparently not in scipy.__all__
	  anymore
	
	* PyARTS/clouds.py: Adapted
	  - Added "from scipy import special", this is apparently not in __all__
	  anymore

	* PyARTS/arts.py, PyARTS/arts_scat.py: Adapted
	  - Use subprocess module, popen is deprecated. Not consistently, only to
	    shut up the unittests.

	* PyARTS/plotting.py: Adapted
	  - Import numy instead of numerix, the latter is deprecated and the
	  former compatible.

2009-06-01  Cory  <cory@pheonix>

	* PyARTS-1-1-33

	* PyARTS/training_data_generator.py (TrainingDataGenerator._extract_nonzero_iwc_T): 
	fix cloudbox limits for profiles with only one non-zero IWC.
	(TrainingDataGenerator.run): fixed print statement.

2009-05-31  Cory Davis  <cory@paddles>

	* PyARTS-1-1-32

	* PyARTS/share/AMSUcloudyBatch.arts.tmplt: updated to Arts 2 format 
	and use fast AMSUB stuff.

	* PyARTS/training_data_generator.py (TrainingDataGenerator.run): move 
	existing ybatch.xml out of the way

2009-05-29  Cory Davis  <cory@paddles>

	* PyARTS-1-1-31

	* PyARTS/training_data_generator.py: for some reason from scipy
	import * does not import io or special.
	
2008-06-20  Cory Davis  <cory@sundog>

	* PyARTS-1-1-30

	* examples/training_data_gen.py: This example script now works, 
	but takes a long time.  Included a plot of the output radiances.

2008-06-18  Cory Davis  <cory@sundog>

	* PyARTS-1-1-29

	* PyARTS/training_data_generator.py: Now works and is somewhat 
	documented. 

2008-06-17  Cory Davis  <cory@ubuntu3>

	* PyARTS/artsXML.py (save): use gzip -f

2008-06-17  Cory Davis  <cory@sundog>

	* PyARTS/training_data_generator.py (TrainingDataGenerator): More work on this
	commiting to work on a faster machine.

2008-06-16  Cory Davis  <cory@sundog>

	* PyARTS/training_data_generator.py (TrainingDataGenerator): Began work on 
	this class.

2008-06-15  Cory Davis  <cory@sundog>

	* PyARTS/artsXML.py (tensor_to_xml): use reshape instead of 
	changing shape directly (not sure why this matters)

2008-06-13  Cory Davis  <cory@sundog>

	* PyARTS-1-1-28

	* PyARTS/artsXML.py (save): enabled saving of gzipped files.
	Also added numpy.int32 to mapping dictionary. (has no effect for now,
	see below)
	(get_arts_type): Nasty catch because for some reason 
	type(_a_numpy_int)==numpy.int32 returns False.

	* PyARTS/artsXML.py (load): enabled loading of gzipped files.

2008-05-28  Cory Davis  <corzneffect@gmail.com>

        * PyARTS-1-1-27

	* PyARTS/artsXML.py: A big refactor of this module. The ARTS data type 
        to save is now determined automatically from the python type. This 
        mapping is specified by the dictionary artsXML.mapping.
        Basically it goes ListType=>Array, numpy.ndarray=>Vector/Tensor, 
        IntType=>Index, FloatType=>Numeric.  
        For instance,        [[1,2,3],[4,5,6]] would be saved as an ArrayOfArrayOfIndex, whereas
        [array([1,2,3]),array([4,5,6])] would be saved as an ArrayOfVector. 
        This has allowed the deletion of several type specific XMLfile.add* methods
        and save* functions.  There is now only one save function and one 
        XMLFile.add method. I think this code looks very nice now.  These changes
        necessitated lots of changes to artsXML calls elsewhere in PyARTS. 


2008-05-28  Cory Davis  <cory@sundog>

        * PyARTS-1-1-26

        * PyARTS/arts_file_components.py: changed the setting of lmax in 
        ppath calculations - this was broken after patricks recent ARTS changes.

        * examples/arts_run_collection.py: fixed for older numpy versions 
        (where the numpy.nonzero return value is different)


2008-04-29  Cory Davis  <cory@sundog>

	* PyARTS-1-1-25

	* Upgrading to numpy 1.04 required quite a few changes (mainly Float to float) 
	and a change to the return of the nonzero function.
	

2008-04-23  Cory  <cory@pheonix>

	* PyARTS-1-1-24

	* All tests now pass after many modifications due to recent arts changes.

2008-04-12  Cory Davis  <cory@sundog>

	* PyARTS/arts_file_components.py (clear_sky_sim_commands):Included 
	setting of y_unit. 

2008-02-10  Cory  <cory@pheonix>

	* PyARTS-1-1-24

	* PyARTS/arts.py (ArtsRunCollection.__init__): generally fixing this up.

	* PyARTS/clouds.py (Gamma.__init__): fixed particle_masses field.

2008-02-07  Oliver Lemke  <olemke@core-dump.info>

	* PyARTS-1-1-23

	* PyARTS/arts_file_components.py: mc_unit is now y_unit.

2008-02-05  Oliver Lemke  <olemke@core-dump.info>

	* PyARTS-1-1-22

	* PyARTS/arts.py:

	Up required version to 1207 for change of Main agenda name to Arts.

	Refine the check whether the current arts version is newer than the
	required version. (Take minor version increments into account)

	* PyARTS/arts_file_components.py:

	Change Main agenda name to Arts for controlfile generation.

	abs_speciesSet is now replaced by SpeciesSet.

	VectorToTbByRJ is now VectorToRJBT.

2007-03-23  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1-1-21

	* examples/arts_run_collection.py: Added, but not yet
	finished!!. This is going to be a comprehensive and hopefully
	instructive example on how to do a large number of cloudy
	simulations with PyARTS.

2007-03-20  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1-1-20

	* PyARTS/arts.py (ArtsRunCollection): Added. The ArtsRunCollection
	class allows you to perform a list of ARTS calculations

	* PyARTS-1.0.124

	* PyARTS/arts_types.py (GasAbsLookup.load): bugfix - was using old
	artsXML.load API.

2005-10-17  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.123

	* PyARTS/plotting.py (SentinelNorm):See SentinelMap 
	(SentinelMap): SentinelMap is a matplotlib colormap that deals
	with data points that you want to distinguish from the rest of the 
	data. For example if bad data is stored as -999, these values are 
	plotted a specified rgb color, and the rest of the colormap (cmap)
	is unchanged.  This needs to be used with the SentinelNorm class. e.g.
	"cmap = SentinelMap(cm.jet, -999, (0,0,0)),norm =
	SentinelNorm(-999),pcolor(x,y,z,norm=norm,cmap=cmap)" will plot
	the data with the usual jet colormap but with bad data values
	(-999) black.

2005-09-20  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.122

	Removed annoying screen output. 

2005-08-18  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.120

	* PyARTS/arts_scat.py (SingleScatteringData.load): updated for
	change to artsXML.load

	updated for change to artsXML.load.

	* PyARTS/arts_types.py (GriddedField3.__call__): bug fix.

2005-08-17  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	(arts_mcgeneral_file): Added.

	* PyARTS/arts_types.py (GriddedField3.__call__): bug fix.

	* PyARTS/arts_file_components.py (safe_latlon_limits): forgot to
	change GriddedField3 statements

2005-08-16  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.118

	* PyARTS/arts_types.py (GriddedField3.__call__): Added. This
	returns the field interpolated on new grids
	p_grid,lat_grid,lon_grid
	(GriddedField3.__init__): Decided that using dictionaries for
	input and storage was not very nice. Now have p_grid, lat_grid,
	lon_grid, and data members.  This prompted changes in lots of
	places (mainly clouds module)

	* PyARTS/arts_file_components.py (safe_latlon_limits):
	Added.Returns safe lat and lon limits for given cloudbox
	parameters and z_field. This can be needed for scattering
	simulations so that no incoming rays can enter the modelled
	atmosphere at a longitudinal or latitudinal face.    Input
	cloud_box: dictionary with keys
	['p1','p2','lat1','lat2','lon1','lon2']; z_field:
	arts_types.GriddedField3 object; Output:
	lat_min,lat_max,lon_min,lon_max
	

2005-08-11  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.117

	* PyARTS/arts_scat.py (phase_mat_fortran): deleted.
	(phase_mat_python): deleted.

2005-08-02  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.116

	* PyARTS/arts.py (ArtsRun.process_out_stream): modified for recent
	arts changes (mc_seed)
	(required_arts_version): updated

	* PyARTS/arts_file_components.py (montecarlo_sim_commands):
	modified for recent arts changes (mc_seed)

2005-07-27  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.115

	* PyARTS/arts_types.py (GasAbsLookup.load): changed call to
	artsXML.load to use use_names=False

	* PyARTS/artsXML.py (newHandler.__init__): added use_names
	argument, which determines whether any present "name"
        attributes are used as keys for each loaded object.
	(load): added use_names argument (default=True)
	(newLoad): deleted - was already deprecated.

	* PyARTS/clouds.py (Droplet): Improved the docstring
	documentation by adding suggested size distribution parameters for
	Stratus and Cumulus Congestus 
	(Droplet.__init__): made Stratus size distribution parameters the
	default.
	
2005-07-26  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.114

	* PyARTS/arts_types.py (GasAbsLookup.__call__): Added. Interpolate
	the lookup table to return a vector containing the contribution of
	each species to the scalar gas absorption coefficient. Before this
	can be called the method set_slidata must be called (only
	once). This is analagous to GasAbsLookup::Extract in ARTS
	(GasAbsLookup.set_slidata): Makes a bunch of sli.SLIData2 objects
	, which enable the lookup of absorption coefficients using
	sequential linear interpolation.
	(GasAbsLookup.calc): Fixed bug - temperature perturbation was not
	being included in the number density calculation.  Now we have
	*exact* agreement with a lookup table provided by Patrick. It
	appears that this problem may also have been in  Stefan's
	create_lookup.m. It might be an idea to check any old absorption
	lookup tables!!!! Also raise error if ARTS1_EXEC is not defined

	* PyARTS/sli.py (SLIData2.interp): raise ValueError if x1,x2 out
	of range

2005-07-21  Cory Davis  <cdavis@staffmail.ed.ac.uk>

        * PyARTS-1.0.113
	
	* PyARTS/arts_types.py (GasAbsLookup.load): Added. loads gas abs
	lookup table from an ARTS1.1. XML file
	
        * PyARTS/artsXML.py (arts_text_names): Added "SpeciesTag" so that
	the load function can deal with GasAbsLookup files

	* PyARTS/arts_math.py (interp1DFieldByZkm): moved import
	arts_types to inside function to avoid circular import problem.

2005-07-13  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.112

	* PyARTS/arts1.py (abs_file): the last species tag group was being
	added twice.

	* PyARTS/arts_types.py (GasAbsLookup.save): forgot closing
	GasAbsLookup tag.

	* PyARTS/__init__.py: updated documentation. GasAbsLookup
	generation is no longer missing!

2005-07-12  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.111

	* PyARTS/arts_scat.py (batch_generate): work around for annoying
	stdout when importing scipy (numerix Numeric 23.1) 
	
	* PyARTS/arts_types.py (GasAbsLookup): Now working!! This class
	enables the calculation of GasAbsLookup tables for arts 1.1.*
	using the stable branch arts 1.0.*. An example of using this class
	will be provided in the ARTS Wiki.
	
	* PyARTS/arts1.py: Added. This module deals with control file
	creation and data input/output for the stable arts 1 package.
	This is used only for the creation of GasAbsLookup tables

2005-07-08  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.110

	* PyARTS/clouds.py (Gamma.scat_calc): and others. changed calls to
	SingleScatterinData.file_gen
	
	* PyARTS/arts_scat.py (SingleScatteringData.calc): Now it is
	possible to specify the complex refractive index (instead of
	relying on Warren etc.) just supply them in the initialisation
	dictionary with the keys 'mrr' and 'mri' the values for these keys
	must be arrays with shape (len(f_grid), len(T_grid)).
	(SingleScatteringData.file_gen): renamed 'save' to make consistent
	with other stuff. 'file_gen' still works but gives DeprecationWarning

	* PyARTS-1.0.109

	* PyARTS/__init__.py (__all__): Added this line which means that
	you can now use "from PyARTS import *", which will import the high
	level modules ['arts_scat','arts','artsXML','arts_math','arts_types',
        'clouds','general','physics','plotting'].  

2005-07-07  Oliver Lemke  <olemke@core-dump.info>

	* PyARTS-1.0.108

	* PyARTS/arts.py:

	If ARTS_PATH is defined use it, otherwise assume that 'arts' is in
	default path. Furthermore, ARTS_PATH must now contain the full path
	including the executable name.

	Raise an ARTSRunError if arts was not found instead of a warning.
	Same if the version requirement is not met.

2005-07-07  Oliver Lemke  <olemke@core-dump.info>

	* PyARTS-1.0.107

	* test/arts_scattest.py:

	Removed obsolete tists CompressTest and Expand1DpndTest.

2005-07-07  Oliver Lemke  <olemke@core-dump.info>

	* PyARTS-1.0.106

	* .cvsignore, data/.cvsignore, examples/.cvsignore, test/.cvsignore:

	Added.

2005-07-04  Oliver Lemke  <olemke@core-dump.info>

	* PyARTS-1.0.105

	* test/cloudstest.py:

	Fixed typo.

	Output extinction coefficient accuracy if assert fails.

2005-07-04  Oliver Lemke  <olemke@core-dump.info>

	* PyARTS-1.0.104

	* PyARTS/arts_scat.py: Don't import no longer existent refr_ind.

2005-06-17  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.103
	  matplotlib-0.82 now a prerequirisite.

	* PyARTS/sli.py (SLIData2.plot): removed call to
	  ScalarFormatterScientific
	
	* PyARTS/plotting.py (ScalarFormatterScientific):removed - this is
	  now properly handled by matplotlib. 

	* examples/plot_refr_ind.py: removed call to ScalarFormatterScientific 

        * PyARTS/plotting.py (myPcolor): With the matplotlib pcolor you
	  actually lose the last row and column of data.  This function
	  addresses this, and produces a pcolor plot where the patches are
	  centred on the x and y values
	

2005-06-08  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.102

	* PyARTS/arts_scat.py: Improved docstring --included an example.

2005-05-24  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.101

	* PyARTS/physics.py (rjbt): Added. Returns the Rayleigh Jeans
	  brightness temperature for a given radiances and frequency(Hz)

	* PyARTS/artsXML.py (newHandler.startElement): Added fix for case
	  when there is more than one ArrayOfSomething in a
	  file. i.e. SLIData2 files. 

	* PyARTS/sli.py (SLIData2.__init__): Added default values for
	  initialisation arguments
	  (SLIData2.load): Added. reads SLIData2 object from an XML file
	  (SLIData2.interp): Added. interpolate SLIData2 at x1 and x2
	  (single numeric values only)
	

2005-05-16  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.100

	* data/ppath[09].ppath.xml: Added. ppath xml files needed by
	  examples/geometry.py
	
	* examples/geometry.py: Added. This example uses the plotting
	  module to draw a cloudbox and some propagation paths. 

	* PyARTS/arts_file_components.py (arts_ppathCalc3D_file): Removed
	  unnecessary commands

	* PyARTS/plotting.py (drawPpath): fixed bug

2005-04-21  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.99

	* PyARTS/arts_scat.py (refice): Allowed temperature extrapolation.

	* src/refr_ind.f: Removed.
	
	* PyARTS/arts_scat.py (tmat_rnd,tmat_fxd): Added check that mri is
	  positive.
	  (refice_bond): Removed.
	  (SingleScatteringData.calc): Removed calls to refice_bond.
	  (ReficeTError):deleted. now a warning is given instead and
	  extrapolation is allowed. 

	* examples/plot_refr_ind.py: Added.  This example uses
	  arts_scat.refice, and the plotting module to plot the
	  real and imaginary components of the refractive index of ice for
	  a range of temperatures at 5 EOS-MLS frequencies.

2005-04-19  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.98

	* INSTALL.txt: Removed LAPACK from the prerequisites list.

	* PyARTS/arts_file_components.py (cloud_box_setup): removed
	  references to za_grid_size, which has been removed from ARTS and
	  was anyhow not needed by MC.

2005-04-13  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* src/lpd.f: Added. This is a lapack fragment, provided by Michael
	  Mishchenko, that performs the
	  job that ampld2.f used to  - i.e. LU factorisation and matrix
	  inversion, that when used by the T-matrix code, greatly
	  increases the convergent range of size parameters and aspect
	  ratios.  So now PyARTS includes this enhanced code, and we no
	  longer need the extra NAG code and the HAVE_NAG environment
	  variable.
	
2005-03-16  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.97

	* README.txt: updated and removed redundancies. 

	* INSTALL.txt: Added. This stuff was formerly in README.txt.

	* PyARTS/sli.py: changed import statements - for some reason they
	  were breaking pydoc.

	* PyARTS/__init__.py: improved docstring.

2005-03-14  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.96

	* PyARTS/arts.py (get_arts_version): Added.  Also added code that
	  uses this function to check that arts is present and that the
	  version is compatible with the PyARTS.arts module

2005-03-10  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS/arts.py (artsGetAtmFields): Fixed bug found by Uli.

2005-03-09  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.94

	* src/tmd_NAG.f,src/tmatrix_NAG.f: removed.

	* PyARTS/__init__.py: improved docstring.

	* PyARTS/test/tmat_limits.py,tmatlimplot.py,print_tmat_limits.py:
	  scripts which calculate, print, and plot the t_matrix convergence
	  limits shown in
	  http://www.sat.uni-bremen.de/arts/wiki/TmatrixConvergence
	

2005-03-08  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.93

	* setup.py: Disabled all HAVE_NAG and HAVE_QUAD switches.  I have
	  discovered that the T-matrix performance with the NAG subroutines
	  can be reproduced using the freely available LAPACK library.  So
	  LAPACK is now a PyARTS prerequisite.  This tidys things up
	  quite a bit.  Now I don't need all the different versions of the
	  T-matrix code, along with the messy process of giving you the
	  extra code if you tell me you have a NAG license.
	  
	  Does anyone actually use
	  PyARTS with HAVE_QUAD=1?  I have disabled it because I don't use
	  it, and I don't know how well it works. Also LAPACK does not
	  have the quad precision routines required.    

	* src/tmd.f,src/tmatrix.f: Changed to ICHOICE=1 and replaced calls
	  to f07*** to zget** (lapack subroutines) 

2005-03-07  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS/arts.py (ArtsRun.process_out_stream): Removed some
	  dependence on defaults.

	* PyARTS-1.0.92

	* PyARTS/arts_file_components.py (defaults): removed more defaults.

	* src/:deleted a bunch of unneeded GSL related files.
	
	* PyARTS/arts_math.py (erf): removed. use scipy.special.erf instead.

	* PyARTS/clouds.py: Replaced all calls to Laguerre.py (and
	  arts_math.erf) with scipy calls.
	
	* PyARTS/Laguerre.py: removed. All of this stuff can be done
	  quicker with scipy.

	* PyARTS/clouds.py (Gamma.pnd_calc): improved docstring.

2005-03-06  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.91

	* examples/MCwith3Dboxcloud.py (arts_params): updated this example
	  to use the incoming_lookup option.

	* examples/mc_incoming_gen.py: removed me-specific file references
	  and replaced with files existing in the PyARTS distribution.

	* PyARTS/arts_file_components.py (montecarlo_sim_commands):
	  updated for recent changes in ARTS.

2005-03-04  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.90

	* PyARTS/clouds.py (Gamma.__init__): moved scipy to the top of the file 
	
	* examples/mc_incoming_gen.py: Added. This example script creates
	  and saves an SLIData2 object suitable for use in ARTS as the
	  "mc_incoming" WSV.  

	* PyARTS/sli.py: Added. includes a python SLIData2 class.  This
	  allows the creation of optimized grids for 2D sequential linear
	  interpolation
	
	* PyARTS/arts.py (create_incoming_lookup): Added. This function
	  initialises an SLIData2 object suitable for the generation of the
	  ARTS WSV mc_incoming.  See examples/mc_incoming_gen.py
	
	* PyARTS/plotting.py: Added. General purpose plotting functions
	  using the matplotlib package. EXPLANATION TO FOLLOW...

	

2005-02-25  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.89

	* PyARTS/arts_file_components.py (tan_z2sensor_poslos): changed an
	  annoying print statement. 

2005-02-24  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS/arts_file_components.py (sensor_setup): Can now supply
	  either rte_pos/rte_los for a single line of sight or filenames
	  for sensor_pos/sensor_los Matrices.  Removed more default parameters.

2005-02-08  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.88

	* PyARTS/arts.py (ArtsRun.refine): Improve the accuracy an already
	  completed ArtsRun (montecarlo only) by adding more photons.

	* PyARTS/arts_file_components.py (defaults): removed some default parameters.

	* PyARTS/arts.py (ArtsRun.process_out_stream): extract
	  mc_iteration_count from ARTS-MC output. fixed bug in y extraction.

2005-01-26  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.87

	* PyARTS/arts_scat.py (SingleScatteringData.filename_gen): Added
	  to extra characters to the part of the filename describing the
	  aspect ratio.  People may have had problems doing simulations with
	  aspect ratios that differ after the 1st decimal place.  If like me
	  you have a big collection of scat data files should either delete
	  them all and start collecting them again or after updating and
	  installing run the script
	  http://www.met.ed.ac.uk/~cory/outgoing/filenamefix 
	  in your $DATA_PATH/scat directory.
	  (SingleScatteringData.load): Added an optional parse_params
	  argument (Default = False).  This will extract the params
          dictionary that was printed in the description field when the file
	  was created 
          This will only work with a file that was created with the arts_scat
          module.

2004-11-19  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.86

	* README.txt: More polishing. 

2004-11-18  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.85

	* README.txt: Added an example and fixed some mistakes. 

2004-11-15  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.84

	* PyARTS/clouds.py (Gamma.scat_calc): Fixed file naming for Gamma
	  single scattering data files.

	* PyARTS/general.py (quickpickle): add -f argument to gzip call.

2004-11-13  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.83

	* PyARTS/clouds.py (Gamma): some bugfixes. 

	* test/cloudstest.py (GammaTest):Added. Tests both the Gamma class
	and the gamma_dist function. 

	* PyARTS/clouds.py (gamma_dist): Added.  Just the function for a
	gamma size distribution.  This is not actually used in he Gamma
	class mentioned previously, but might be generally useful, and is
	used in test/cloudstest.py. Again, this requires scipy.

2004-11-12  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.82

	* PyARTS/clouds.py (Gamma): Another hydrometeor class.  Gamma
	distribution of either liquid or ice particles. Unfortunately this class
	requires scipy (I am considering making scipy a prerequisite for
	PyARTS; this would tidy things up a bit - much of arts_math would
	become redundant and I could lose some of the c extension
	modules. If anyone has an opinion on this I would like to hear
	it). So far Gamma is untested. 

2004-11-11  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.81

	* test/arts_scattest.py (MishchenkoBenchTest.testCylinder):
	Added. tests against the scattering amplitude matrix benchmark
	calculations published in Mishchenko,2000.
	(MishchenkoBenchTest.testSpheroid): Added. These should give us
	some confidence in the PyARTS single scattering properties.

2004-11-09  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.80

	* PyARTS/general.py (quickunpickle): can now deal with gzipped
	pickle files. Just specify a filename ending with '.gz'
	(quickpickle): can now create gzipped pickle files. Just specify a 
	filename ending with '.gz'

2004-11-05  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.79

	* PyARTS/arts_file_components.py (arts_ppathCalc3D_file): Fixed.
	Now it works.

	* Changelog: fixed previous entry.

2004-11-04  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.78

	* PyARTS/arts.py: Improved docstring.

	* test/testdocs.py: Added. This checks that all the command line
	examples given in the docstrings actually work.

	* PyARTS/__init__.py: Improved docstring.

2004-11-02  Cory Davis  <cdavis@staffmail.ed.ac.uk>
	
        * PyARTS/arts_file_components.py (arts_ppathCalc3D_file): Added.

2004-11-01  Cory Davis  <cdavis@staffmail.ed.ac.uk>

	* PyARTS-1.0.76

	* README.txt : Improved introduction. Much of this has now been
	copied to the ARTS Wiki.

	* PyARTS/PyARTS.py: renamed arts.py.  This was confusing.

	* examples/get_atm_fields.py (Q): changed reference to
	PyARTS module.

	* examples/MCwith3Dboxcloud.py (my_run): changed reference to
	PyARTS module.

2004-10-26  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.75

	* PyARTS/clouds.py (Droplet.__init__): Fixed a problem reported by
	Sreerekha.  It looks like I had been distracted at a crucial moment when
	originally writing this.  The expression that determines the pnd_field was
	only half finished.  The Droplet test mentioned below verifies that
	this is now fixed.

	* PyARTS/Laguerre.py (laggausdata): Improved docstring. 

	* test/cloudstest.py (DropletTest): Tests the accuracy of the
	pnd_fields and scattering properties produced by the Droplet class. 

	* PyARTS/artsXML.py (load): raise IOError if file not found

2004-10-15  Cory Davis  <cory@geosl504>

	* PyARTS-1.0.74

	* examples/MCwith3Dboxcloud.py:changed for recent arts changes.  

	* PyARTS/PyARTS.py (artsGetAtmFields):changed artsXML.newLoad to 
	artsXML.load. 
	(ArtsRun.process_out_stream): changed for recent arts changes.
	This is still very ugly, and should be changed to something like
	the baby ArtsRun class in arts/tests/testall.py

	* PyARTS/arts_types.py (ArrayOfGriddedField3.load): changed
	artsXML.newLoad to artsXML.load.

	* PyARTS/arts_file_components.py (get_z_max): changed
	artsXML.newLoad to artsXML.load.
	(montecarlo_sim_commands): updated for recent arts changes.

	* test/artsXMLtest.py: Added.

	* PyARTS/artsXML.py (newHandlerTest): removed.
	(newLoad): renamed load. newLoad now raises a DeprecationWarning
	and calls load.
	Improved module docstring.
	(Handler.__init__): Added DeprecationWarning
	(NewHandlerTest): Moved to test/artsXMLtest.py

2004-10-11  Cory Davis  <cory@fog>

	* PyARTS-1.0.73

	* PyARTS/PyARTS.py (artsGetAtmFields): made silent and improved
	error handling.  Improved docstring.

	* PyARTS/arts_file_components.py (gas_species_setup): Fixed for
	special case gas_species==[].

2004-10-08  Claudia Emde  <claudia@sat.physik.uni-bremen.de>

	* PyARTS-1.0.72
	
	* PyARTS/clouds.py (Cloud.boxcloud_1D): Added. Can be used to
	generate 1D box clouds.

2004-10-07  Cory Davis  <cory@fog>

	* PyARTS-1.0.71

	* PyARTS/clouds.py (MonoCrystal):Added this class.  Represents a
	  monodispersion of ice particles.  Used in exactly the same way as
	  Crystals and Droplets. (i.e added to Cloud objects using the
	  addHydrometeor method). Shifted old testcase to test/cloudtest.py

2004-10-04  Cory Davis  <cory@geosl504.met.ed.ac.uk>

	* PyARTS-1.0.70

	* PyARTS/arts_file_components.py: Innumerable changes provoked by
	  recent arts changes.  All tests now work.

	* PyARTS/PyARTS.py: Innumerable changes provoked by recent arts
	  changes.
		
	* PyARTS/arts_scat.py (tmat_fxd,tmat_rnd):  An upgrade to f2py or
	  gcc caused the these functions to produce spurious errors.  The
	  errmsg variable that is passed from the fortran extension
	  modules now contains some whitespace characters even when there
	  is no actual convergence failure.  This has been resolved for
	  now with the error check being "if (len(errmsg.strip())>0):"
	  instead of "if (len(errmsg)>0):".  One day I should look for a
	  better way of dealing with errors in the fortran modules.

2004-10-03  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.69

	* PyARTS/arts_types.py (GasAbsLookup.calcFromArts1): Began work on
	  this - I want to be able to calculate gas_abs lookup tables with
	  python. Nowhere near finished yet. 

	* PyARTS/PyARTS.py (artsGetAtmFields): Needed this for the above.

	* examples/get_atm_fields.py: Added.

2004-09-28  Cory Davis  <cory@fog>

	* test/examplestest.py (ExamplesTest.testExamplesRunWithNoErrors):
	  Added this file.  This checks that all of the example scripts in
	  /examples run without error.

	* PyARTS/PyARTS.py (ArtsRun): renamed arts_run ArtsRun, to make
	  naming scheme consistent (initial caps for classes, lc for
	  functions)
	
	* examples/: Added

	* examples/MCwith3Dboxcloud.py: Added. Simple example of 3D box
	  cloud generation and MC radiative transfer

	* test/testall.py: typing 'python testall.py -v' will run all of
	  the unit tests.  This is a compulsory step before committing any
	  changes to PyArts.

	* test/arts_mathtest.py: removed Cory specific file references.

	* data/: Added.  Holds data required for testcases and examples

	* data/tropical.*.xml: Added. Also added files necessary for
	  examples/MCwith3Dboxcloud.py 
	
	* test/cloudstest.py: removed Cory specific file references.

	* setup.py (include_dirs): removed reference to
	  $HOME/include/python.  This was originally there to locate the
	  Numeric header files, but this location is somewhat user specific.
	  People who have numpy installed in the standard place will not
	  notice this difference.  Others, like me, will need to use the
	  --include-dirs command line argument.  Installing PyARTS will
	  then involve:
	  
	  'python setup.py build_src build_ext
	  --include-dirs=<somepath>/include/python install --home=~'

2004-09-27  Cory Davis  <cory@fog>

	
	* PyARTS-1.0.67 

	* PyARTS/arts_file_components.py: deleted alot of cory specific stuff

	* PyARTS/clouds.py (Droplet): Improved documentation 

	* PyARTS/__init__.py: Added README.txt documentation

	* PyARTS/PyARTS.py: Improved docstring 


2004-09-16  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.66

	* PyARTS/arts_scat.py(tmat_fxd,tmat_rnd): fixed bug that only
	  occurs when T-matrix code does not converge. Removed tests from
	  this module and put them in tests/arts_scattest.py

	* test/arts_scattest.py:Added, and included a test for proper
	  behaviour with T-matrix convergence failures. 

2004-09-16  Cory Davis  <cory@fog>

	* PyARTS-1.0.65

	* MANIFEST.in: Fixed problem in source distribution generation reported by
	  Patrick.
	

2004-09-15  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.64

	* doc/arts_scat.txt: Added.  This is a reStructured text document
	  for use with the docutils package.  This will be the format for
	  the User Guide, Algorithm Description and Theoretical Basis
	  Document.  This will allow the straighforward inclusion of
	  docstrings, and output to latex/pdf and html.

	* doc/makehtml.sh: Added

	* doc/makelatex.sh: Added.


2004-09-16  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.63 Made PyARTS into a package in the true python
	  sense.  This involved moving all of the modules from the base
	  directory to a new PyARTS subdirectory, creating an __init__.py
	  file, modifying setup.py, the test files, and scat_file_batch.
	  This has tidied up the installation and pydoc documentation.
	  The PyARTS modules are now installed to ~/lib/python/PyARTS
	  (instead of ~/lib/python/ -you should delete the old
	  files). This tidies things if you have a lot of other 
	  python stuff or if you have done the default install as root.
	  The only difference for usage now is that in your scripts,
	  instead of "import arts_scat", it is now "from PyARTS import
	  arts_scat"; or instead of "from general import *", it is now
	  "from PyARTS.general import *".  For people new to python I
	  think this makes it clearer now in scripts what stuff is from
	  PyARTS, and what is from the rest of the python library.  This
	  change has been tested with all available tests on my laptop. 


2004-09-14  Cory Davis  <cory@fog>

	* PyARTS-1.0.62

	* arts_file_components.py (atmosphere3D_settings): Added

	* test/cloudstest.py: Added.  from now on tests will go in this
	  directory, with the filename <modulename>test.py. To run the
	  test go python cloudstest.py -v. Other tests will gradually
	  moved from the modules to here.
	
	* clouds.py (boxcloud): added. Returns a box shaped Cloud object
	  with specified dimensions and constant IWC.

	* arts_math.py (interp): made to work also for lists and arrays(1-D).

2004-09-08  Cory Davis  <cory@fog>

	* PyARTS-1.0.59

	* arts_types.py (GriddedField3.load): use artsXML.NewLoad instead
	  of artsXML.load. The next step will be to rename artsXML.newLoad...

	* arts_scat.py (SingleScatteringData.load): use artsXML.NewLoad instead
	  of artsXML.load. Also fixed test cases.

	* PyARTS.py (arts_run.process_out_xml): use artsXML.NewLoad instead
	  of artsXML.load.

2004-08-29  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.55

	* arts_scat.py (tmat_fxd): Added. This is a simplified interface
	  to the tmatrix.tmatrix[q] functions.  Elsewhere, finished 
	  implementation of
	  quad precision T matrix code, including the addition of two
	  test cases, *QuadRandomTest* and *QuadFixedTest*.  Allowed input
	  of temperatures below the refractive index function limits, to
	  enable ARTS-safe temperature grids.

2004-08-25  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.54
	
	* arts_scat.py (tmat_rnd): Added. This is a simplified interface
	  to the tmd.tm[dq] functions.  Also began work on a testcase
	  QuadRandomTest.
		

2004-08-24  Cory Davis  <cory@fog>

	* PyARTS-1.0.53
	
	* physics.py (vapour_P_ice): Fixed.  There was an error in the
	  documentation from which I obtained this function.

2004-08-24  Cory Davis  <cory@fog>

	* PyARTS-1.0.52
	
	* physics.py (vapour_P_ice): Added.

2004-08-13  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.51

	* arts_scat.py (BatchTest): Updated

	* src/tmatrixq.f, src/tmq.f, src/tmatrixq_NAG.f, src/tmq_NAG.f,
	  src/tmq.par.f, laheybuild.sh: Added quad precision code, which
	  has been successfully installed with the lahey lf95
	  compiler. The laheybuild.sh script builds the package using
	  lf95.  To enable a quad precision build set the HAVE_QUAD
	  environment variable to 1.  If you have a NAG license you should
	  also obtain the file ampld2q.f from me (I cant really include
	  this in the cvs for licensing reasons)

	* src/tmd.f, src/tmd_NAG.f (tmd): fixed an optimization dependent
	  problem in the original tmatrix code that could occur with the
	  parameter nkmax=-1.
	
	* setup.py: Added code for including quad stuff. 

2004-08-09  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.50

	* clouds.py (Droplet.scat_calc): Changed the output scattering
	  data file name generation. 

2004-08-05  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.49

	* clouds.py: made T_grid a property of the hydrometeor classes and
	  removed from scat_file_gen and scat_calc calls.  This is because
	  ice and liquid will require different T_grids.

	* arts_scat.py (SingleSCatteringData): moved refractive index
	  calculation from __init__ to calc

2004-08-03  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.48

	* clouds.py: Removed stuff that is now obsolete thanks to the
	  change in ARTS.  We have now only three classes: Cloud, Droplet,
	  and Crystal.  Improved docstrings.

2004-07-30  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.47

	* clouds.py (NewCloud,Droplet,Crystal): Added new classes to
	  reorganise the way cloud fields and scattering properties are
	  generated. Eventually these will make much of the existing clouds
	  module obsolete, but old classes (eg Cloud, Hydrometeor) will
	  remain in the meantime

	* Laguerre.py: Added. This module performs several flavours of
	  Gaussian quadrature (including Laguerre Gauss). This is useful
	  for handling particle size distributions.  At some point this
	  module may be merged with arts_math.

	* arts_types.py (GriddedField3.__setitem__,GriddedField3.pad): Added.

2004-07-22  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.46

	* clouds.py (mh97): Because we want the output n to be in
	  m^-3micron(radius)^-1) it needed to be multiplied by 2.

2004-07-12  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.45

	* arts_math.py (lag_gauss): Added.

2004-07-07  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.44

	* arts_math.py: added constant LagGaussData for Laguerre-Gauss
	  quadrature
	

2004-07-07  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.43

	* arts_file_components.py (arts_clear3D_file): Added.

	* PyARTS.py (arts_run): Added 'clear3d' run type.

2004-07-06  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.42

	* PyARTS.py (arts_run): Temporarily disabled the feature the
	  previous change.  Same old problem with popen and threading.

	* clouds.py (Cloud3D.pnd_field_gen): Fixed bug

2004-07-02  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.41

	* arts_scat.py (refice_bond): Added (wrapper to refr_ind). Also
	  fixed test_suite.

	* arts_file_components.py: Made fixes necessitated by Patricks
	  recent changes.

	* PyARTS.py (arts_run): now deal with arts errors by opening
	  stderr pipe (using popen3) and raising an exception if anything
	  comes down it.

2004-07-01  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.40

	* arts_scat.py (SingleScatteringData) __init__(), calc(),
	  file_name_gen(): Modified to allow non-singleton T_grids

	* src/refr_ind.f: re-added to cope with temperatures outside range
	  allowed by REFICE

	* clouds.py (Cloud3D): Added. Generates arts files for given 3D
	  IWC and/or LWC fields!

	* setup.py: re-added refr_ind module.

2004-06-28  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.39

	* doc/arts_scat.tex: Added Algorithm Description and Theoretical
	  Basis section.

2004-06-26  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.38

	* arts_scat.py (batch_generate): Fixed small bug - num_proc was
	  not begin passed to multi_thread2

	* clouds.py (Cloud1D): created this class for Sreerekha

2004-06-11  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.37

	* arts_scat.py (SingleScatteringData.__init__): Added input check
	  for 'phase' keyword.  Now use the Gauss legendre integration for
	  ptype=30 for numerical integration over orientations and for
	  calculation of Kabs.  This is a huge improvement - reduces the
	  time taken in the test_suite by a factor of 20 AND significantly
	  improves the accuracy.

	* arts_math.py (gaus_leg,multi_gaus_leg): Gauss Legendre
	  quadrature, and a multi dimensional version.  I wish I had done
	  this earlier.   

2004-06-10  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.36

	* arts_scat.py (SingleScatteringData): Added an optional precision
	  argument for the *calc* and *generate* methods.  This determines
	  the precision of the tmatrix and tmd, T-matrix functions, and
	  all of the numerical integration involved (for ptype=30). The
	  default (and RECOMMENDED) value is 0.001.
	  SingleScatteringData objects can now be initialised with the
	  keyword 'phase', with valid values: 'ice' or 'liquid'.

	* src/tmatrix.f, src/tmatrix_NAG.f, tmatrix.pyf (tmatrix): Added
	  DDELT as an input argument to allow the *precision* argument
	  mentioned above. 

	* clouds.py: Changed all phase argument references from 'water'
	  to 'liquid'.

	* doc/arts_scat.{tex,pdf}: Updated.

2004-06-08  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.35

	* arts_math.py (vanilla_mc,multi_qromb): Added. Two multi dimensional
	  integration functions

	* arts_scat.py (SingleScatteringData.calc). Implemented
	  arts_math.multi_qromb for calculation of K_abs.  This has fixed
	  the inaccuracy ini this calculation (at a
	  cost). arts_scat.test_suite runs through perfectly now.

2004-06-04  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.34

	* scat_file_gen: more fiddling with pipes

	* clouds.py: After some tests, made some bug fixes.  Added usage
	  example in docstring.

2004-06-03  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.33

	* general.py (multi_thread2): Removed try - except.

	* clouds.py (Cloud.scat_data_combine): debugged. Seems to work OK now.

2004-06-02  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.32

	* general.py (multi_thread2): Added. Much more elegent version of
	  multi_thread. Will replace multi_thread eventually. 

2004-06-02  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.31

	* general.py (multi_thread): minor changes to hopefully deal with
	  Cloud.scat_file_gen problem. 

2004-06-01  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.30

	* clouds.py: Documentation.

	* BUGS.txt: Added.

	* scat_file_batch: Played about with this because
	  Clouds.scat_file_gen is hanging.  Same for
	  arts_scat.batch_generate
	

2004-05-31  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.29

	* clouds.py (Clouds.scat_file_combine): small change so that we
	  don't try to combine empty lists of scattering data. And added
	  some documentation.

2004-05-28  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.28

	* arts_math.py (locate): fixed bug

	* clouds.py (Clouds.scat_file_combine): implemented condensing of
	  scattering data for mixed phase and different ptypes

2004-05-12  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.27

	* clouds.py (Clouds): Began a major overhaul, which will enable
	  the efficient representation of mixed phase clouds with multiple
	  habits. Renamed *Habit* class *Hydrometeor* and added the data
	  member phase ('ice' or 'water')

	* arts_scat.py (SingleScatteringData.__init__): Added type check for
	  aspect ratio parameter. Also added 'return self' to several methods.

2004-05-11  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.26

	* clouds.py (nioku): Fixed normalisation of particle number
	  density function. (nioku_int): Fixed bug in last size bin limits.

2004-05-10  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.25

	* clouds.py (nioku_int):Added. provides a binned cloud water
	  distribution by integrating *nioku* over each size bin. There
	  seems to be some inconsistency in the normalisation of the nioku
	  function
	

2004-05-09  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.24

	* arts_math (gosper):Added. This is a good cheap approximation to the
	  gamma function

	* clouds (nioku):Added. This is a particle size distribution for
	  water droplets in clouds.

2004-05-04  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.23

	* arts_scat.py (refliquid): Added. Calculates the refractive index
	  for liquid water, as per the EOS-MLS code. 

2004-04-22  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.22

	* phys_const.py: Moved to physics.py and added function vapour_P. 
	  Changed all references to phys_const module.

	* arts_file_components: Reduce memory use by a factor of four in
	  montecarlo simulations by setting scat_za_grid and scat_aa_grid
	  to zero length vectors (these were causing ScatteringInit to
	  create giant i_field and scat_field tensors, which Monte Carlo
	  simulations don't actually use 

2004-04-21  Cory Davis (rsh)   <cory@fog>

	* PyARTS-1.0.21

	* clouds.py (Cloud.set_T_grid): Removed code that changed the
	  temperature field if temperature is below the REFICE input
	  limits. This issue is now dealt with in Cloud.scat_file_gen. 

2004-04-21  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.20

	* clouds.py (Cloud): Added class.  Made Cumulonimbus, Anvil, and
	  Tower subclasses

	* PyARTS.py: Added global constants ARTS_PATH, which is determined
	  by an environment variable with the same name (HOME/arts is
	  default), and ARTS_EXEC(=ARTS_PATH/src/arts)

	* general.py (arrayfromascii): Added headlines (default= 0)
	  argument to deal with text headers

2004-04-15  Cory Davis  <cory@zvi.jpl.nasa.gov>

	* PyARTS-1.0.19

	* clouds.py (Cumulonimbus.clearHabits): Added. Function obvious.

	* artsXML.py (newLoad): Removed annoying prepending of DATA_PATH

2004-04-14  Cory Davis  <cory@zvi.jpl.nasa.gov>

	* PyARTS-1.0.18

	* PyARTS.py (p20_p30SphereCompTestCase): Removed because it relies

	  a DATA_PATH/scat directory

2004-04-08  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.17

	* clouds.py (Cumulonimbus.pnd_field_gen): Modified to account for
	  annoying feature in ARTS (pnd_field covering whole atmosphere)

	* PyARTS.py (arts_run.run_parallel): Added return self

2004-04-07  Cory Davis  <cory@fog>

	* PyARTS-1.0.16

	* clouds.py (Habit): Added this class which simplifies the
	  implementation of microphysics in 3D cloud
	  scenarios. (Cumulonimbus) Added methods *addHabit*,
	  *scat_file_combine*, *pnd_field_gen*. Modified *scat_file_gen*
	  to account for the Habit class. (mh97) changed arguments to be
	  more ARTS friendly

	* arts_scat.py (SingleScatteringData.load): Added return self.

2004-04-06  Cory Davis  <cory@fog>

	* PyARTS-1.0.15

	* clouds.py (mh97):Added. This returns the McFarquhar and
	  Heymsfield particle size distribution for a given IWC,
	  temperature, and array of particle diameters

	* src/erfc.c, src/check.h, src/cheb_eval.c, src/chebyshev.h ,
	  src/eval.h, src/error.c, src/stream.c, src/erfc_wrap.c
	  src/gsl/*: A whole bunch of GSL files needed to make the erfc
	  extension required by clouds.mh97

	* arts_math.py (erf): added. Matlab equivalent.

2004-04-05  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.14

	* scat_file_batch: Fixed bug

	* arts_scat.py (batch_generate): Use multi_thread instead of
	  multi_proc.

	* general.py (multi_proc): Removed.  Realised that the same can be
	  achieved, with more flexibility, by using multi_thread.

2004-04-05  Cory Davis  <cory@fog>

	* PyARTS-1.0.13

	* refice.pyf, arts_scat.py: renamed refice extension module REFICE
	  and added a python wrapper function for the refice function, which
	  includes python exceptions for input range errors and uses
	  frequency instead of wavelength as an input variable.

	* general.py (multi_proc): prepend 'nice ' to the command.

	* scat_file_batch: the scattering data file is now only generated if
	  one by the same name does not already exist

	* tmatrix.pyf, tmatrix.f, tmatrix_NAG.f, arts_scat.py: Added
	  errmsg output variable to the tmatrix function to signal
	  convergence problems. (This has already been done for tmd)

2004-04-02  Cory Davis  <cory@fog>

	* PyARTS-1.0.12

	* scat_file_batch: changed output command to
	  cPickle.dump(a.filename,sys.stdout) 

2004-03-31  Cory Davis  <cory@fog>

	* PyARTS-1.0.11

	* general.py (multi_proc,multi_thread, test_suite,
	  multi_thread_test): Implemented is_empty Event for job queues
	  (much better than while not queue.empty() pass). Added test_suite
	  with multi_test_thread.

2004-03-31  Cory Davis  <cory@fog>

	* PyARTS-1.0.10

	* general.py (multi_proc): Fixed bug.

	* src/REFICE.f, src/refice.pyf: Added. The refice extension
	  incorporates the refractive index calculation of Warren, Gao, and
	  Wiscombe

	* setup.py: Added refice extension and removed refr_ind

	* arts_scat.py (batch_generate): try - except to catch invalid
	  scat_file_batch output.

2004-03-30  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.9

	* arts_scat.py (SingleScatteringData.calc): included code to
	  append scattering parameters to file when a T-matrix conversion
	  error occurs. This information will be used to define the range
	  of applicablility of the double precision code.

	* src/tmd.f, src/tmd_NAG.f: removing babble with the QUIET argument.

2004-03-30  Cory Davis  <cory@fog>

	* PyARTS-1.0.8

	* arts_scat.py (SingleScatteringData.filename_gen): Modified this
	  function so that SingleScatteringData files go in the directory
	  $DATA_PATH/scat
	
	* clouds.py (Cumulonimbus): Added member functions *scat_file_gen*

	* general.py (multi_proc): Added input variable logging which
	  works in the same way as in the multi_thread function

	* src/tmd.f, src/tmd.pyf (tmd): Added *quiet* input variable to
	  eliminate babble. 

2004-03-29  Cory Davis  <cory@fog>

	* PyARTS-1.0.7

	* clouds.py (Cumulonimbus): Added member functions *set_p_grid*,
	  *set_T_grid*, *set_IWC_grid*, which will be used to generate
	  single scattering properties and pnd files for ARTS simulations.
	  These functions take a filename argument which points to a
	  GriddedField3 file.

2004-03-26  Cory Davis  <cory@fog>

	* PyARTS-1.0.6

	* clouds.py (Anvil,Tower,Cumulonimbus):Added member functions
	  *get_extent*, *save*, *autogrid*.

2004-03-25  Cory Davis  <cory@fog>

	* PyARTS-1.0.5

	* clouds.py: Added. This module includes classes representing 3D
	  clouds and their components. So far we have a Cumulonimbus class
	  which comprises an Anvil object and a Tower object.  The
	  *discretize* method returns a gridded field (of ones and zeros)
	  representing the shape of the cloud, for given
	  lat_grid, lon_grid and z_grid.  From here it
	  shouldn't be too hard to create pnd fields for ARTS simulations.

2004-03-24  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.4

	* arts_scat.py (SingleScatteringData.calc): incorporated analytic
	  orientation averaging for the extinction matrix in the ptype=30
	  case for prolate particles.

2004-03-23  Cory Davis  <cory@localhost.localdomain>

	* PyARTS-1.0.3: Added avg_tmatrix.f as source for tmatrix
	  extension module. This performs analytic orientation averaging
	  of the T-matrix as described by Mishchenko(1991). This can be
	  used to give an exact orientationally averaged extinction
	  matrix. Modified setup.py accordingly

	* src/tmd.f: Bug fix.

2004-03-23  Cory Davis  <cory@met.ed.ac.uk>

	* PyARTS-1.0.2: Added README.txt. renamed ampld.par.f -> tmatrix.par.f
	  and changed include statements in tmatrix.f tmatrix_NAG.f.

2004-03-21  Cory Davis  <cory@met.ed.ac.uk>
	
        * PyARTS-1.0.1: Added this file, also made separate T matrix 
	  source files for NAG and non-NAG distributions. Modified setup.py
          so that the environment variable HAVE_NAG (0 or 1) determines
          which source files to use.
