CATALOG Astro

        The ASTRO catalog format is one of the two following ones:

    A comma separated value file, including the frequency, the species name, and
    the transition name, e.g.:
          150E3; MOLE; TRANSITION;

    A list-directed file, with the same information, e.g.:
          150E3 'MOLE' 'TRANSITION'

    Lines  beginning  with  an exclamation mark are considered as comments.  The
    first line **MUST** be a comment line (or just start by a ;) That  line  may
    specify  the  unit of Frequencies in the catalog (Hz, kHz, MHz, GHz).  If no
    recognized unit is found in this line, frequencies are assumed to be in MHz.

    A default catalog (with no implied  warranty)  is  given  in  gag_data:mole-
    cules.dat.
