Changes Introduced in V5.4-0

The following describes the most significant changes which occurred in the AST library between versions V5.3-2 and V5.4-0:

  1. the FitsChan class now has an option to support reading and writing of FITS-WCS headers that use the -TAB algorithm described in FITS-WCS paper III. This option is controlled by a new FitsChan attribute called TabOK. See the documentation for TabOK for more information.

  2. A new class called ``Table'' has been added. A Table is a KeyMap in which each entry represents a cell in a two-dimensional table.

  3. A new class called ``FitsTable'' has been added. A FitsTable is a Table that has an associated FitsChan holding headers appropriate to a FITS binary table.

  4. KeyMaps can now hold byte values. These are held in variables of type BYTE.

  5. KeyMaps have a new attribute called KeyCase that can be set to zero to make the handling of keys case insensitive.

  6. a memory leak associated with the use of the AST_MAPPUTELEM<X> functions has been fixed.

  7. A new method called AST_MAPRENAME has been added to rename existing entry in a KeyMap.
