The following describes the most significant changes which
occurred in the AST library between versions V7.3.2 and V7.3.3:
- The FitsChanFitsChan class has new attributes CardNameCardName and CardCommCardComm, which hold
the keyword name and comment of the current card.
- When using the FitsChan class to read FITS-WCS headers that include
polynomial distortion in the SIP format, any inverse transformation specified
in the header is now ignored and a new inverse is created to replace it based
on the supplied forward transformation. Previously, an inverse was created
only if the header did not include an inverse. The accuracy of the inverse
transformation has also been improved, although it may now be slower to
evaluate in some circumstances.
