* Updates the HeaderletHDU class to use PyFITS's new FitsHDU class as its base.embray2011-11-082-408/+337
| | | | | | | | | | | | | | | | | | | | | | This works mostly the same way as the old implementation. The differences are as follows: * The headerlet data is no longer needlessly encapsulated in a tar file; instead it's included directly as an embedded FITS file which should work fine for most FITS readers (though most won't know what to do with it, and will just treat it as raw data). * A few new keywords are included in the HeaderletHDU's header--these keywords (the XINDn keywords) give the offsets of each HDU embedded in the HeaderletHDU. Howver, this information is not currently used. * In addition to the `.headerlet` property the `.hdulist` property is provided, which returns the HeaderletHDU's contents as a normal `HDUList` object instead of a `Headerlet` object. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@13979 fe389314-cf27-0410-b35b-8c050e845b92
* This revision fixes problems with WCSCORR table updates; specifically, hack2011-11-072-31/+70
| | | | | | | | | | | | | | - added fit keywords (rms*,nmatch,catalog) to SIPWCS header in headerlet for use in updating WCSCORR - changed definition of FIT_KW to get values from SCI header, not PRIMARY - changed calls to finding blank rows to also use rows with wcs_id='0.0' as a blank row. This also required updating the logic to support multiple selection criteria - implemented update of WCSCORR by wcskey value - get FIT keywords from full header, not just HSTWCS header - only update columns which have been defined (for backward compatiblity with WCSCORR tables with columns that have since been removed from the definition) These changes have been tested to insure that the RMS values get updated in the WCSCORR table properly from the SCI image as well as from the headerlet. They also make sure the headerlet gets updated with the correct values. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@13971 fe389314-cf27-0410-b35b-8c050e845b92
