OUTSEQ -1.0 9999.0 Output UV file name (seq. #)
OUTDISK 0.0 9.0 Output UV file disk unit #.
BMAJ 0.0 Major axis in asec

Task: When you make a model using a Clean image (UVSUB with CMODEL =
'IMAG'), the resulting uv data have their amplitudes reduced by
the Fourier transform of the Clean beam (neglecting the
contribution of the residual image after Clean). This task
will correct amplitudes for this using a Clean beam provided
either with adverbs BMAJ, BMIN, BPA or from a second input
catalog image file.
INNAME.....Input UV file name (name). Standard defaults.
INCLASS....Input UV file name (class). Standard defaults.
INSEQ......Input UV file name (seq. #). 0 => highest.
INDISK.....Disk drive # of input UV file. 0 => any.
IN2NAME....Clean image name. Used if BMAJ and/or BMIN is zero.
IN2CLASS...Clean image class
IN2SEQ.....Clean image sequence number.
IN2DISK....Clean image sequence number.
OUTNAME....Output UV file name (name). Standard defaults.
OUTCLASS...Output UV file name (class). Standard defaults.
OUTSEQ.....Output UV file name (seq. #). 0 => highest unique
OUTDISK....Disk drive # of output UV file. 0 => highest with
space for the file.
BMAJ.......Clean beam major axis in asec
BMIN.......Clean beam minor axis in asec
BMAJ.......Clean beam position angle in degrees
WEIGHTIT...If < 1 AND> 0, take the correction fator to the WEIGHTIT
FACTOR.....Maximum correction factor: < 2 => 1000. The correction
used is MIN (correction computed, FACTOR).
