         This is wrong!  Floating numbers have only a suitable number
of digits, but all strings are reproduced.  The easiest way to specify
all calibrators is with CALCODE.  CALSOUR is hard to type for more
than a few since AIPS input lines are limited to 80 characters.
CALSOUR(i) ='xxx' can be done, but is a pain.  CALCODE is the way to
go, with CALSOUR all blank.

       If it showed 7 it used 7 only.

       These are small and should be ignored

         This is not small and should be edited.
