CMODEL
Type:  Adverb  (String*4)
Use:   To select the source of the model used to compute the fringe
       visibilities of the source model.
       'COMP' uses a Clean components table
       'IMAG' uses an image.
       '    ' uses COMP if a CC file is present, else IMAG.
Null value:
       ' '  => task chooses
Tasks:
   BLCAL.........Compute closure offset corrections.
   BLCHN.........Compute closure offset corrections on a
                 channel-by-channel basis.
   BLING.........Find residual rate and delay on individual baselines.
   BPASS.........Computes spectral bandpass correction table.
   CALIB.........Determines the calibration to be applied to a uv data
                 set given a model of the source.
   CPASS.........Computes polynomial spectral bandpass correction table.
   FRING.........Fringe fit data to determine antenna calibration,
                 delay, rate.
   KRING.........Fringe fit data to determine antenna calibration,
                 delay, rate.
   LPCAL.........Determines instrumental polarization for UV data,
   OOSUB.........Subtracts/divides a model from/into a uv data base.
   PCAL..........Determines instrumental polarization for UV data.
   RLCAL.........Determines instrumental right-left phase versus time (a
                 self-cal).
   UVCON.........Generate sample UV coverage given a user defined array
                 layout.
   UVSUB.........Subtracts/divides a model from/into a uv data base.
Procedures:
   OOCAL.........Determines antenna complex gain with frequency-
                 dependent models.
   OOFRING.......Fringe fit data to determine calibration with spectral
                 index options.
   VLBABPSS......Computes spectral bandpass correction table.
