* This update to STWCS includes the following revisions:hack2011-05-032-15/+18
| | | | | | | | | | | | | | - add EXTVER keyword to WCSCORR table extension in 'init_wcscorr()' - revised how pad rows are defined when creating a WCSCORR table - added logic to only work with NPOLFILE and D2IMFILE related keywords in input files that have been updated to use those reference files - added logic to only delete WCS's from IMAGE extensions to avoid problems of trying to delete a WCS from a table extension git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@12710 fe389314-cf27-0410-b35b-8c050e845b92

* The logic for finding an empty (matching) row in ↵hack2011-04-121-3/+5
| | | | | | 'wcscorr.find_wcscorr_row()' was modified to strip blank characters from the end of each element before comparing. This allows the '==' comparison to actually match a blank string and find the rows to be filled. The fix allows the WFC3/IR demo datasets (8 WFC3/IR images) to be processed by betadrizzle. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@12456 fe389314-cf27-0410-b35b-8c050e845b92

Removed support for the destim arg from `applyHeaderlet()`, as it was not used anywhere. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@12446 fe389314-cf27-0410-b35b-8c050e845b92

* Various cleanup and small bug fixes. In particular, init_wcscorr() now ↵embray2011-04-054-245/+305
| | | | | | 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). git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@12393 fe389314-cf27-0410-b35b-8c050e845b92
* The HSTWCS method 'wcs2header' was modified to append the SIP and IDC ↵hack2011-04-052-16/+15
| | | | | | | | | | | | 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. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@12392 fe389314-cf27-0410-b35b-8c050e845b92

I originally wanted the `HeaderletHDU.data` attribute to transparently return the Headerlet object itself (rather than a long binary string), but that doesn't work due to the way pyfits currently writes files. So instead the Headerlet object can be accessed from the `HeaderletHDU.headerlet` attribute. * Other miscellaneous cleanup git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@12346 fe389314-cf27-0410-b35b-8c050e845b92

This allows the method to use a simple (limited) for loop for the iterations instead of a potentially infinite while loop, while generally requiring much fewer than 10 iterations as opposed to over 350 for the fit on the sky. The added complication, though, is that this method now relies on a linear WCS derived using the 'utils.output_wcs()' function. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@12004 fe389314-cf27-0410-b35b-8c050e845b92

The algorithm used was based on the code from drizzle's task 'tranback'. This method has been checked using WFC/IR image with SIP and ACS/HRC image with SIP+NPOLFILE such that the RA/Dec positions for a few random positions can be returned to within a delta close to the error limit (<<0.001 pixels).
