| | | | | | This was found by Ray when running 'tweakreg' on ACS/HRC data, with the problem and subsequent fix being verified using ACS/HRC dither box data. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@14014 fe389314-cf27-0410-b35b-8c050e845b92
* Updates the HeaderletHDU class to use PyFITS's new FitsHDU class as its base.embray2011-11-081-16/+16
| | | | | | | | | | | | | | | | | | | | | | 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
* The WCSCORR table update will not crash anymore (based on my testing) when ↵hack2011-11-041-0/+6
| | | | | | WCSNAME is missing from the image PRIMARY WCS. This required adding a new function to define the default WCSNAME value based on the IDCTAB so that it could be called upon initialization of the table, and when updating it if WCSNAME is missing. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@13961 fe389314-cf27-0410-b35b-8c050e845b92
* The API for 'updatewcs.utils.extract_rootname()' was changed, along with all ↵hack2011-11-012-9/+14
| | | | | | calls to the function in STWCS, to allow it to strip off a user-specified suffix. The default behavior would be replicate current (old) behavior. This update fixed unwanted differences that showed up in the betadrizzle regression tests. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@13934 fe389314-cf27-0410-b35b-8c050e845b92
* Updates to STWCS correct the following problems:hack2011-10-311-12/+5
| | | | | | | | | | - DISTNAME value now generated without recursively stripping everything after the underscore by relying on fileutil.buildNewRootname() - error message for 'attach_to_file()' expanded to provide specific reason for failure - primary header keywords now updated, rather than inserted, by 'updateRefFiles()' to eliminate the problem with creating duplicate keywords git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@13932 fe389314-cf27-0410-b35b-8c050e845b92

* Merging changes from 'stwcs_hdrlet' branch (r18787 - r13909) into trunk. ↵hack2011-10-253-13/+55
| | | | | | This version of STWCS (0.9.1) provides support for headerlets based on 'Headerlet Design' wiki document, and includes TEAL interfaces for all public headerlet functions. It also moves the TEAL interface for 'updatewcs' from 'astrodither' to this package. The TEAL interaces have been included as a new 'gui' sub-package in order to keep them separate from the remainder of the package's functionality. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@13910 fe389314-cf27-0410-b35b-8c050e845b92
* Refined the definition of the 'SIPNAME' and 'DISTNAME' keyword values to ↵hack2011-08-301-2/+3
| | | | | | properly reflect that the distortion model is specific to each input image. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@13698 fe389314-cf27-0410-b35b-8c050e845b92
* The 'createDgeoHDU' and 'createNpolHDU' methods in 'udpatewcs' were updated ↵hack2011-08-192-2/+29

* Corrected the generation of the WCSNAME keyword to use ↵hack2011-08-191-1/+1
| | | | | | 'utils.extract_rootname', so that the same conventions can be used and to eliminate problems that generate values such as 'IDC_./n7n18501j'. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/trunk/stwcs@13647 fe389314-cf27-0410-b35b-8c050e845b92

* The code for 'updatewcs' was revised to correctly add the NPOL related ↵hack2011-08-151-2/+6
