Here are some initial thoughts: Don't know about good, but given some 2dF data FITS2NDF will make lots of structures. Likewise a former TWODSPEC app might be another possibility, as Tim Wilkins liked the baroque data structures, but that has a Figaro interface in the way. How about one of the former SPECDRE tasks like FITGAUSS on some ACSIS spectral cube as this needs to store the fits? Is the SPECDRE extension like this http://www.starlink.ac.uk/docs/sun86.htx/node48.html what you have in mind? Malcolm -- Scanned by iCritical.
