STWCS 1.7.2

Fixed a bug affecting data with no astrometry database solutions.

STWCS 1.7.1

• Filenames for new headerlet files based on updated/new
  IDCTABs now based on hash of WCSNAME instead of WCSNAME itself. [#183]

STWCS 1.7.0

• Make the code more robust when defining extname attribute of a WCS for multi-extension FITS files when their primary header contains 'EXTVER' keyword but not the 'EXTNAME' keywords. [#179]
• Fix a bug in stwcs.wcsutil.altwcs.archive_wcs due to which a str type ext would raise an exception. [#177]
• Modify updatewcs to insure that the distortion keywords remain in the same part of the primary header as the rest of the calibration reference file names. [#175]
• Update build_reference_wcs to accept list of filenames as well single filenames or a single HDUList object as input. [#173]
• Add support for computing new a priori WCS solutions when running updatewcs. [#170]
• Add new parameter to updatewcs to limit the astrometry database WCSs appended to the file to only those based on the same IDCTAB as specified in the image header. [#170]

Add new parameter to updatewcs to specify whether or not to remove duplicate headerlet extensions from the FITS file when updating the image using the astrometry database. [#172]

STWCS 1.6.1

• Fix a bug in wcsutil.wcscorr.init_wcscorr() that would result in crash when run on drizzled images that do not have OPUS WCS (WCS key 'O'). [#165]
• Make WCS and headerlet name comparisons case-insensitive when applying headerlets. [#163]
• Deprecate accuracy argument in all_world2pix and replace it with tolerance in order to have compatible function signature with astropy's all_world2pix()'. [#166]

STWCS 1.6.0

This release includes improvements to the process of updating headers with solutions from the astrometry database.

• When updating from a headerlet, the Primary WCS is archived only if not already archived
• When updating from a headerlet, t he Primary WCS is not archived if the distortion models differ.
• Tweakreg specific keywords are archived with the alternate WCS.
• General clean up and improvements to keywords and keyword comments.

For details see CHANGES.rst.

STWCS v 1.5.3

• Correct a problem where best WCS solutions were not applied with repeated reruns of updatewcs.
• Correct the logic for replacing a headerlet with one which has a different distortion model.
• Add stdout to logging handlers.

STWCS-1.5.1

Changes

• Stwcs 1.5.1 requires stsci.tools >= 3.5.2.

• Allow updatewcs to be called with HDUList objects as input.

• Update the XML parser for the astrometry database and switch the default to use
  the MAST TEST server which is publicly accessible.

• Gracefully ignore when the astrometry database returns an empty result for
  an image.

• Fixed a bug in converting a PC to a CD matrix.

STWCS 1.4.2

Bug fix release:

• Fix installation script
• Fix a bug in restoring headerlets from a HeaderletHDU to a SCI extension [#60]
• Fix logic to gracefully handle lack of any WCS solutions from the astrometry database for an exposure. [#62]
