FIT BEAM_SIZE

        BEAM_SIZE is a Real array of size 3 containing the user-specified values
        for  the Clean beam size, with BEAM_SIZE[1] the Major axis, BEAM_SIZE[2]
        the Minor axis (both in arcsec) and BEAM_SIZE[3] the Position angle  (in
        degrees, North towards East).

        If  BEAM_SIZE[1]  and BEAM_SIZE[2] are 0, the CLEAN or FIT commands will
        determine the Clean beam size (available in variable BEAM_FITTED similar
        to BEAM_SIZE) by adjusting the dirty beam main peak.

        If  only  one  of  BEAM_SIZE[1] and BEAM_SIZE[2] is non zero, it will be
        used as the Clean beam size for a circular beam.

        If both are non zero, BEAM_SIZE totally specifies the Clean  beam  size.
        BEAM_FITTED is thus set to the BEAM_SIZE values when used.
