MODEL

        [CALIBRATE\]MODEL [Arg1 [... ArgN] [/MINVAL Value [Unit]]
      [/MODE CCT|IMAGE|UV_FIT [Frequency]]

      This command creates model visibilities from Clean  components,  Clean
    images or UV_FIT  results from the last UV_FIT command, depending on the
    /MODE option. If the option is not present, the default mode is  CCT  or
    UV_FIT,  depending  whether  CLEAN  (or its specialized versions HOGBOM,
    CLARK, etc...) or UV_FIT was done last.

      The current UV data is used to define the visibility sampling and data
    weights. It should have only one channel, or the same number of channels
    as the specified model.

      The resulting UV data is available in SIC structure UV_MODEL.  It  can
    be  written using WRITE UV_MODEL, or selected for further use using com-
    mand  UV_SELECT.   MODEL  and  UV_RESIDUAL  are  complementary  commands
    (UV_DATA = UV_MODEL + UV_RESIDUAL).

    For the Clean component the syntax is
        [CALIBRATE\]MODEL  [MaxIter] [/MINVAL Value [Unit]] [/MODE CCT [Fre-
    quency]]
    It computes visibilities on the current UV sampling using a source model
    made of the MaxIter first Clean Components, or of all pixel values above
    the given Value if /MINVAL is present.

    For the Clean image, the syntax is
        [CALIBRATE\]MODEL [ImageName] [/MINVAL Value [Unit]] [/MODE IMAGE]
    (ImageName is currently dummy. It will be used to specify any  available
    3-D Image variable later.)

    For the UV_FIT results, the syntax is
        [CALIBRATE\]MODEL [F1 .. Fn] [/MODE UV_FIT]
    which  computes  a model using the F1, ..., Fn fitted functions (default
    all) for the current UV sampling.

      UV_MODEL can also be selected by using command UV_SELECT  for  further
    imaging by UV_MAP (and thus UV_RESTORE) or display by SHOW UV.
