Previous: Changes Introduced in V5.3-1
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 FitsChan class that could cause wavelength
axes to be assigned the units ``m/s'' when reading WCS information from a
FITS header.
- The
AST_SET routine
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
FrameSet being read by astRead.
- The KeyMap class has a new attribute called ``SortBy''. It controls
the order in which keys are returned by the
AST_MAPKEY
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.
INTEGER*2)
values.
