gh_mirror/jhunkeler/stwcs_hcf.git/wcsutil/hstwcs.py, branch 1.2.4

Redoing the r13221-13223 merge in the actual trunk now. This updates trunk to the setup_refactoring branch (however, coords, pysynphot, and pywcs are still being pulled from the astrolib setup_refactoring branch. Will have to do that separately then update the svn:externals)

Updated `update_wcscorr()` to be more flexible and general-purpose. It can

now apply WCS keywords to the WCSCORR table even from extensions in a different
file from the one containing the WCSCORR table.  This might break any existing
code using either it, or `archive_wcs_file()`.`

Various cleanup and small bug fixes. In particular, init_wcscorr() now works what I believe to be 'correctly'--it applies all existing WCSs from the SCI extension headers to the new WCSCORR table in the correct order (wcs_key w/ 'O' first; extver).

The HSTWCS method 'wcs2header' was modified to append the SIP and IDC distortion model keywords to the header using the '.update()' method instead of extending the header with a CardList. This corrected a problem with the CardList not fully updating the original header making the appended cards unaccessible using the dictionary lookup syntax.

The logic for using the 'readModel()' method of HSTWCS was also improved to not try and read the IDCModel when no 'idctab' had been specified in the header.  

Finally, a small bug was fixed in the 'wcscorr' module for recognizing what rows are available for being updated so that the update will actually occur.

This update to the HSTWCS class in STWCS attempts to address a couple of issues: namely, makes recognition of non-HST data more general (slightly) and only applies distortion model in all_sky2pix when it is present. The first change should allow HSTWCS to be run on data created with IRAF's artdata package/task.

some of the IDC model kw are not used, do not store them in the header. Do not archive ORIENTAT in alternate WCSs but recompute it every time a WCS is restored.

wcslib.wcsini populates the WCS struct which includes 'RESTFRQ' and 'RESTWAV'. Remove them when writing it to headerhstwcs.py
