SPECX2NDF has been revamped so that it now uses the new AST SpecFrame functionality, allowing translation between spectral frames without re-running SPECX2NDF. The SPECTRUM parameter (and associated parameters SOR, DOPPLER) are no longer required since they can be changed after conversion using WCSATTRIB application. Scripts using SPECX2NDF may need modification. In addition to dealing with map files SPECX2NDF has now been extended to deal with SPECX data files; each spectrum in the file is translated to an NDF spectrum in the output HDS container file.
FITS2NDF supports INES archive IUE spectra.
Improved propagation of existing world co-ordinate system (WCS) headers in NDF2FITS partially from improvements to the AST subroutine library. For example, long-slit spectra with a three-dimensional WCS, but stored in a two-dimensional image, retain their three-dimensional WCS headers. Comments are preserved where values have not changed significantly.
The references to the old VMS-only tasks have been removed from the
documentation because the residual VMS service no longer exists.
