The resulting files can be saved on tape in FITS format for later use. Be sure to save the data before your disk reservation expires. Saving data on tape requires generating a catalogue with the filenames to be saved, this is done with the command
CREATE/ICAT catname dirspec
Files in this catalogue will be copied on tape as follows
OUTTAPE/FITS catname tapeunit
The output tape will be in FITS format, 1 block per record, and 1600 bpi density. Look into the command help for other options.
