The following describes the most significant changes which
occurred in the AST library between versions V7.3.1 and V7.3.2:
- Fix support for reading FITS header that use a GLS projection.
Previously, an incorrect transformation was used for such projections if
any CRVAL or CROTA value was non-zero.
- The KeyMapKeyMap class has new sorting options “KeyAgeUp” and
“KeyAgeDown” that retain the position of an existing entry if its value
is changed. See the SortBySortBy attribute.
- A bug has been fixed in the FitsChanFitsChan class that caused CDELT keywords
for sky axes to be treated as radians rather than degrees when reading a
FITS header, if the corresponding CTYPE values included no projection code.
