FIT FixedValues

        Clean beam parameters can also be specified by the users, by loading
    the BEAM_SIZE array with values other than its default  values  (0,0,0).
    In this case, no automatic fit will be performed.

    In general, we discourage this usage, as it may result in a very improp-
    er flux scaling if the beam size is inappropriate. This mode  should  be
    reserved  to  special cases where the beam cannot be properly fitted, or
    to have a circular beam by taking as beam size the geometrical  mean  of
    the fitted major and minor sizes.

    Fixing  the  beam  size  should be associated to the FIT /JVM command to
    minimize (but not suppress !...) errors in total flux scaling.
