`pyhetdex` release notes¶

Development version @ trunk¶

Removed default 1.3 degree rho stage rotation. Default is now to apply no rotation in coordinates/astrometry.py

Changes to the selection function model
Modified code to read in three fiber-extracted noise files, rather than a datacube

Fix fplane parser inconsistencies between documentation and implementation (issue #2117)
Remove some deprecated module (issues #1841, #2119, #2120)
telescope.py: new model type to the FWHM and normalisation servers.
Make skip_comments more robust in regards of special characters (Bug #2305)
db_helper: add support for peewee 3 (issue #2344)

Remove modules deprecated in v0.10.0 (issues #1641, #1676, #1677, #1349)
pyhetdex.coordinates.astrometry: add option to use the IFUCen file (issue #1962) and to pass dither offsets (issue #1968)
use configparser package in python 2 to backport python 3 implementation (issue #1979)
move some functionality to get files from a distribution and copy them from VDAT (issue #1963)
added --rhozp option to astrometry routines, to allow user to specify the rotation angle of the rho stage
Add pyhetdex.tools.db_helpers (from VDAT, issue #2026)
add FileNameRotator (from VHC, issue #2032)

Added routine to create an overview plot for one exposure
Override configurations from the, e.g., the command line (issue #1849)
Added tool to generate masks, i.e. corners of each IFU in a focal plane for a list of shots (issue #1873)

pyhetdex.ltl.chebyshev: added; matrixCheby2D_7 function added (gregz)
Made modifications to add_ra_dec based on Karl/Greg’s feedback
Added xy_to_ra_dec function that reads in-IFU positions and returns ra, dec
pyhetdex.tools.configuration: ConfigParse.{get_list,get_list_of_list}: don’t cast forcefully anymore (issue #1620, #1621). Not backward compatible
copy tangent_projection_astropy into tangent_projection (issue #1636)
deprecate some module and mark others as not tested/possibly changing (issue #1637)
fplane parser: skip IFU by SLOTID (issue #1617) or when the SPECID/IFUID is marked as empty (issue #1618)
fplane parser: fix properties according to their documentation (issue #1640)
fix case when DITHER header key is not present or not set (issue #1674)
cast list index to integer to comply with numpy >=1.12 (issue #1769)

pyhetdex.cure.distortion: Added write routine and tests
pyhetdex.cure.fibermodel: Added interpolation routines
pyhetdex.cure.fiber_fractions: Computes the fill factor of apertures by fibers, expected to be useful in any model of how likely you are to detect and LAE
pyhetdex.coordinates.astrometry: Command line tools to add ra, dec to catalogues from VIRUS. Also a tool to add a 2D WCS to datacubes/apimages, but this is still a work in progress.
pyhetdex.het.telescope: update the Shot class according to issue #1515; remove the illumination and image quality servers as they are not used
pyhetdex.het.dither: pass the dither positions or a file with them from the command line (issue #1544)
pyhetdex.het.dither: add the possibility to use the hetpupil executable when creating dither files

pyhetdex.cure.distortion: make Distortion class compatible with multiple file versions. Supports version 14 and 17
pyhetdex.cure.fibermodel: make FiberModel class compatible with multiple file versions. Supports version 16 to 21
pyhetdex.cure.psfmodel: make PSFModel class compatible with multiple file versions. Supports version 2 and 3.
update fplane file to new format (issue #1460)
fix bug with distance calculation

pyhetdex.het.reconstruct_ifu.QuickReconstructedIFU: change interface to ease reconstructing science images in VDAT. WARNING: non backward compatible change

Deprecate pyhetdex.doc.sphinxext.todo; use the version shipped with sphinx>=1.4 in the module sphinx.ext.todo
Processes: add DeferredResult class for defer function execution when running single processor jobs and allow to pass it to the _Worker object

First version of tools to generate random catalogues; work in progress
tools.processes: added function to remove a worker from the internal storage. Useful for instance to clear closed/terminated workers
het.dither: executable dither_file improved and adapted for use with the output of ccdcombine

pyhetdex.tools.configuration: more functionalities backported from python 3.4 to python 2.7
pyhetdex.tools.files.file_tools: better error messages when compiling regex
documentation: add the version of pyhetdex
