    Deconvolve a Mosaic or Single-field using the current METHOD (in  SIC  vari-
    able  METHOD).   See INPUT CLEAN for the other SIC variables controlling the
    deconvolution process.  Supported methods are CLARK, HOGBOM, MRC, MULTISCALE
    and SDI. Use HELP CLEAN Method and/or HELP CLEAN METHODNAME for further  de-
    tails on each algorithm.

    Clean  the specified plane interval (default: planes between variables FIRST
    and LAST). If only FirstPlane is specified, Clean  only  that  plane.   This
    command   allows   a   per-plane  definition  of  the  convergence  criteria
    CLEAN_NITER and CLEAN_ARES.

    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 possi-
    ble,  a sensible value of each parameter will automatically be computed 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.
