The following describes the most significant changes which
occurred in the AST library between versions V5.3-1 and V5.3-2:
- A bug has been fixed in the FitsChanFitsChan class that could cause wavelength
axes to be assigned the units “m/s” when reading WCS information from a
FITS header.
- The
astSetastSet function
now allows literal commas to be included in string attribute values. String
attribute values that include a literal comma should be enclosed in quotation
marks.
- A bug in FitsChan has been fixed that caused “-SIN” projection
codes within FITS-WCS headers to be mis-interpreted, resulting in no
FrameSetFrameSet being read by astReadastRead.
- The KeyMapKeyMap class has a new attribute called “SortBySortBy”. It controls
the order in which keys are returned by the
astMapKeyastMapKey
function. Keys can be sorted alphabetically or by age, or left unsorted.
- Access to KeyMaps holding thousands of entries is now significantly
faster.
- KeyMaps can now hold word (i.e.
short integer)
values.
