gh_mirror/jhunkeler/stwcs_hcf.git/lib/stwcs/wcsutil, branch release_1.1.2

STWCS update to insure that NEXTEND keyword (if already present in primary header) remains consistent with full size of FITS file after updates.

Updated API for stwcs.wcsutil.hstwcs.HSTWCS.all_sky2pix() to accept both 1-D arrays for Ra,Dec and a single 2-D array to be consistent with pywcs.WCS.all_pix2sky().

This resolves #1076.

Very minor/simple update to HSTWCS.all_sky2pix() method to not update output values based on an increasingly bad inversion. This only affects positions at an extreme distance outside the frame where the distortion model breaks down and becomes unstable.

Fixed a bug introduced in r26987 to the headerlet module that caused headerlet.apply_as_primary to fail when the headerlet was created directly using the Headerlet class and an HDUList as input.

STWCS v1.1.2: This update only includes changes to the headerlet module and related TEAL interface modules. The changes include:

2013-10-23T20:40:19+00:00

  - Fix calls to PyFITS to allow writing of headerlet out to files
  - Implement support for multiple file inputs for apply_header, delete_headerlet and attach_headerlet TEAL tasks and their underlying Python interfaces.  (Ticket #1063)

The docstrings for all updated headerlet functions were updated to reflect the new input capabilities.

Interface with 'new' PyFITS (>v3.1.x) and its writeto() method were corrected with this change. This allows the Headerlet class to work again to create new headerlets.

Problems with using apply_headerlet_as_primary() on WFPC2 data have been corrected in this revision. These included counting the D2IM arrays correctly and eliminating a typo for a variable. These changes were tested using both a WFPC2 image and the same ACS image that demonstrated the previous bug.

The apply_as_primary() method of the Headerlet class was revised to look for the correct WCSDVARR (and D2IMARR) extensions from the headerlet. This finished the process where the PyWCS generated object was updated to include the image-specific EXTVER values for each of the WCSDVARR and D2IMARR extensions.

2013-08-27T17:43:15+00:00

These changes were successfully tested (manually) on the regression test case where the problem was first reproduced after being alerted to this problem by Shireen when trying to document the apply_headerlet_as_primary() function.

Replace hdu._extver' with 'ext.ver' because of changes to pyfits' API.
