The following describes the most significant changes which
occurred in the AST library between versions V1.8-3 and V1.8-4:
- The FitsChanFitsChan class has a new attribute called DefB1950DefB1950 which can be
used to select the default reference frame and equinox to be used if
a FitsChan with foreign encoding contains no indication of the
reference frame or equinox.
- A bug has been fixed in the FitsChan class which could prevent
astWriteastWrite from creating a set of FITS headers from an otherwise valid
FrameSetFrameSet, when when using FITS-AIPS encoding.
- A bug has been fixed in the FitsChan class which could cause
astReadastRead to mis-interpret the FITS CROTA keyword when using FITS-AIPS
encoding.
