 * Revision 1.4  2005/08/29 11:53:26  rwiegand
 * Added function to determine UVOT raw window from FITSHeader object.
 *
 * Revision 1.3  2005/07/18 12:41:58  rwiegand
 * Allow caller to require UVOT raw window to be loaded from WINDOW*
 * keywords.  Allow caller to store UVOT raw window to WCS keywords.
 *
 * Revision 1.2  2004/12/02 22:12:52  rwiegand
 * Pass create_primary_header a FileSpec to take the basic header from.
 *
 * Revision 1.1  2004/12/02 21:29:45  rwiegand
 * A Swift/UVOT tool library.
