This option will open the catalog file 'name'.CAT, assuming it fol-
lows the format of OBSINP catalogs in use on the 30m Radiotelescope of
IRAM. A file 'name'.SOU will be created in the current directory in the
Plateau de Bure format, so that this option needs to be specified ONLY
ONCE for each catalog. Fancy options such as SL0P, SB0P ... are not sup-
ported.
