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.
