FIT

        [CLEAN\]FIT [Plane] | [CHANNEL First Last] [FIELD First Last]
      [/THRESHOLD Value] [/JVM_FACTOR [NoCircle]]

    Fit the dirty beam to obtain the clean beam parameters.

    For single fields, "FIT Plane" can be used to fit just one of the possi-
    ble Frequency dependent beam planes. Note that the number of beam  plane
    can be different from that of image channels.

    For  mosaics,  dirty  beams can be up to 4-D, depending on Frequency and
    Field number.  Keywords CHANNEL (or equivalently PLANE) and FIELD  allow
    to restrict the fit to the specified range of Channels or Field numbers.
    All ranges are considered

    Note that an automatic FIT is performed by  all  CLEAN  algorithms  when
    needed.   The  appropriate  Frequency  plane corresponding to each image
    channel is used.  For mosaics, CLEAN takes the  average  of  the  fitted
    beam parameters on all fields.

    User specified values can be used instead (see HELP FIT FixedValues).
