CALSOUR
Type: Adverb  (String*16, 30 elements)
Use:  Standard data selection adverb, used to specify a list of
      calibrators to be included in or excluded from an
      operation.  If the first character of ANY element is "-"
      then all named calibrators are excluded else all named
      are included.  All must be left justified.  All blanks
      mean all calibrators  are selected.
Null Value:  ' '
      All null value usually means take all calibrators; null
      values after a non null value are ignored.
