    Instruct CLEAN to start from the specified Clean Component Table  stored  in
    the specified File, or those currently in memory if no File is given.

    This  can  be  used  to re-start a Clean that was not deep enough. It can be
    used to split the Clean operation in several steps,  possibly  changing  the
    support at each step, or even the Clean METHOD.

    For  spectral  data, the starting model should have the same number of chan-
    nels, or have only 1.  The later capability can be used to  start  from  the
    Clean  Components derived from a Continuum-only data set, so that deconvolu-
    tion proceeds to find out the line-only structure. This is an alternative to
    separate deconvolution of Continuum and continuum-subtracted  data  followed
    by addition of the Clean images.
