UV_RESIDUAL

            [CLEAN\]UV_RESIDUAL [MODE] [Arg1 ... ArgN] [/FIELDS List]

          This  command  subtract  Clean components OR fit results from the last
        UV_FIT command, depending on specified argument MODE if present (can  be
        CLEAN  or UV_FIT), or on whether CLEAN (or its specialized versions HOG-
        BOM, CLARK, etc...) or UV_FIT was done last if not. The residual UV data
        are  available in SIC structure UV_RESIDUAL, and can be written by WRITE
        UV_RESIDUAL command.

          The UV_RESIDUAL data can also  be  selected  for  further  imaging  by
        UV_MAP  (and  thus  UV_RESTORE)  or  displayed  by SHOW UV using command
        UV_SELECT.  MODEL and UV_RESIDUAL are complementary commands (UV_DATA  =
        UV_MODEL + UV_RESIDUAL); see HELP UV_RESIDUAL Note however.

        For the Clean component the syntax is
            [CLEAN\]UV_RESIDUAL [CLEAN] [Niter]
        that  subtracts  the Niter first (default all) Clean Components from the
        UV data.

        For the UV_FIT results, Clean component the syntax is
            [CLEAN\]UV_RESIDUAL [UV_FIT] [F1 .. Fn]
        that subtracts the F1 to Fn fitted functions (default all) from  the  UV
        data.
