The following describes the most significant changes which occurred in the NDF_ system between versions V1.3 and V1.4 (not the current version):
Note that this constitutes only a preliminary introduction of WCS facilities to the NDF library, mainly to permit the writing of data format conversion applications that support WCS information. Descriptions of the new routines are included in this document, but the main text does not yet contain an overview of the WCS facilities, for which you should consult SUN/210 at present. Further recommendations on the use of AST with the NDF_ library will be given in future, once experience with the new facilities has been gained.
