        Make and deconvolve maps starting from a UV table.  It  combines  UV_MAP
        and CLEAN in a single step.

        The mapping process is identical to UV_MAP.  It makes a map from UV data
        by griding the UV data using a convolving function, and then Fast Fouri-
        er  Transforming the individual channels.  However, MX always produces a
        single beam for all channels, thus neglecting frequency  change  between
        channels.   MX  enables to shift the map center and rotate the image, by
        shifting the phase tracking center and rotating the  UV  coordinates  of
        the input UV table.

        The  CLEAN  algorithm is similar to the CLARK method, but with major cy-
        cles operating directly on the ungridded UV table rather than in the im-
        age  plane. Accordingly, aliasing affects only of the residuals, not the
        clean components. It is thus more accurate but also slower than CLARK as
        it  asks  for the gridding step at each major cycle.  MX also shares the
        same limitation as CLARK on large sidelobes.

        The user can control the algorithm through SIC variables. New values can
        be given using "LET VARIABLE value". For ease of use, and whenever it is
        possible, a sensible value of each parameter will automatically be  com-
        puted from the context if the value of the corresponding variable is set
        to its default value, i.e. zero value and empty string. A few  variables
        are initialized to "reasonable" values.

            [CLEAN\]CLEAN ?
        Will  list  all  main CLEAN_* variables controlling the CLEAN parameters
        for the current METHOD.

        HELP CLEAN Variables will give a more complete list.

                    [CLEAN\MX ?
            Will list all MAP_* and CLEAN_ * variables controlling the MX param-
        eters.
