MODEL

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