FITS\READ [File0me] [/CHECK]
This command is used to Read data from FITS format. Not all FITS tapes
may be read by CLASS, and some header information might be incomplete
when doing so.
On tape, the new scan is read from current tape position, and the tape
is left at the beginning of next file. On disks and CDroms, the file
name argument is compulsory.
Option /CHECK can be used to list the header while reading the file.
