CALDIR:   Verb to list all calibration source models available
DATAIN                             To select Perley models from
                                   the web '2014', '2019'
----------------------------------------------------------------
CALDIR
Type:      Verb
Use:       Displays a list of all calibration models that may be read
           in with task CALRD.

      The Perley models are found on ftp.aoc.nrao.edu in directories
      pub/staff/rperley/MODELMAPS and pub/staff/rperley/MODELMAPS2019.
Adverbs:
  DATAIN....If DATAIN begins with 'PERLEY' and contains 2014 or 2019
            or is simply '2014' or '2019', then the available models
            listed are those found on the web in Rick Perley's 2014
            or 2019 model sets.
            Any other value looks in the standard $AIPSTARS area on
            the local computer.

For the JVLA we are going to produce models at more closely spaced
frequencies.  One band so far has this done
