* This update to STWCS includes the following revisions:hack2011-05-031-12/+13
| | | | | | | | | | | | | | - 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

| | | | | | extension version numbers (I should look into fixing that). This makes sure that each headerlet HDU appended to a file is given a sensible extension version by default. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@12459 fe389314-cf27-0410-b35b-8c050e845b92

| | | | | | | | | | sensibly. It allows users to specify a name for the headerlet generated from a file, but if hdrname is not specified a sensible default is still used. 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
* `Headerlet.apply()` now appends the headerlet of the original WCS to the *end*embray2011-04-061-11/+24
| | | | | | | | | | | | of the file's HDU list. And it now also applies the new headerlet to the HDU list under that, and update's the WCSCORR table with rows for the WCSs in the new headerlet. This should achieve most of the basic requirements for headerlet functionality, though I still need to look into reversing the application of a headerlet... git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@12398 fe389314-cf27-0410-b35b-8c050e845b92

| | | | | | 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
* * Added compression supportembray2011-04-011-26/+58
| | | | | | | | | | | * Had to add the standard NAXIS, BITPIX, etc. header keywords in order for pyfits to correctly determine the HeaderletHDU data size. * Added a monkey patch so that pyfits can recognize the HeaderletHDU type when opening a FITS file; naturally this module has to be imported for headerlet support to be available. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@12387 fe389314-cf27-0410-b35b-8c050e845b92
* Headerlet work:embray2011-03-311-202/+355
| | | | | | | | | | | | | | | * Moved several functions into the Headerlet class * Started work on the HeaderletHDU class--this is a non-standard extension HDU type for representing the tarred headerlet file that is appended to a file that has that headerlet applied to it. 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
