[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).
