MODEL

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

      This  command  creates model visibilities from Clean components, 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 command
    UV_SELECT.  MODEL and UV_RESIDUAL  are  complementary  commands  (UV_DATA  =
    UV_MODEL + UV_RESIDUAL).

    For the Clean component (CCT) mode, 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 IMAGE mode, the syntax is
        [CALIBRATE\]MODEL [ImageName] [/MINVAL Value [Unit]] [/MODE IMAGE]
    If ImageName is not specified, the CLEAN image is used instead.

    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 imag-
    ing by UV_MAP (and thus UV_RESTORE) or display by SHOW UV.
