HELP SECTION

CDCAL
Task:  CDCAL reads an SN table to find the scalar average amplitude as
       a function of antenna and IF.  It then copies CD table CDVER
       writing new values to version max+1.  Values are the input CD
       table value times the square of the SN table gain.

Adverbs:
  INNAME.....Input image name (name).       Standard defaults.
  INCLASS....Input image name (class).      Standard defaults.
  INSEQ......Input image name (seq. #).     0 => 1.
  INDISK.....Disk drive # of input image.   0 => any.
  SNVER......Version number of input SN table, 0 => highest
  CDVER......Input CD table (Cal device) version number, 0 -> max.
  TIMERANG...Limit averaging of SN values to this time range.
             0 or end < start => all
  AVOPTION...'MIN' -> uses the minimum gain amplitude
             'MAX' -> uses the maximum gain amplitude
             else uses the average gain amplitude
  PRTLEV.....> 0 causes message file writing of all values
             changed:  CD in, SN gain, CD out
  PRTLIMIT...Limit PRTLEV output to PRTLIMIT lines.  0 -> 1000
