UV_MAP Mosaics

        [CLEAN\]UV_MAP [[CenterX CenterY Unit] [ANGLE AngleValue]
      /FIELDS FieldList [/TRUNCATE Fraction]

    The  UV  data  can be a Mosaic UV table. In this case, UV_MAP will image the
    Mosaic, using appropriate primary beam size and truncation level.

    By default, the primary beam size is taken from  the  telescope  parameters,
    either  as  found in the telescope section of the UV table and the observing
    frequency (e.g. for ALMA it uses 1.13 Lambda/D). If  absent,  the  telescope
    section information can be added by command SPECIFY TELESCOPE.

    The truncation level (in fraction of peak) for individual pointings is taken
    from  variable MOSAIC_BEAM or from the /TRUNCATE option argument.  It should
    be 0 for high dynamic range. Non zero values may be  used  with  caution  in
    case of large pointing errors, but require sufficient overlap of the fields.

    The imaging method can be GUETH (default) or SAULT, see the MOSAIC command.
