RESTFREQ
Type: Adverb    (array(2))
Use:  To specify the spectral-line rest frequency in Hertz.  RESTFREQ
      is an array to allow greater precision in the specified value.
      The rest frequency is taken to be RESTFREQ(1) + RESTFREQ(2) with
      both values converted to double precision before adding.  For
      example, the frequency 1420.405752E6 is too precise for a single
      adverb.  However, RESTFREQ = 1420.4E6, 5752. will convey the
      desired value correctly.  NOTE, if RESTFREQ(1) = RESTFREQ(2),
      then the rest frequency is taken to be just RESTFREQ(1).
Null value: none
Verbs:
  ALTDEF.....Define an alternate description in velocity units
             of a frequency axis.
Tasks:
   SETJY.....Task to enter source info into source (SU) table.
