Task: Does Complex Hogbom CLEAN
Adverbs:
INNAME......The dirty map image name. Standard defaults.
The real and imaginary parts of the input image
must have names 'QIM001' and 'UIM001' respectively.
INSEQ.......The dirty map image sequence number. 0 => high
INDISK......The dirty map image disk drive no. 0 => any
BLC.........The third and higher dimensions are used to
specify the plane in the dirty and residual
images to be processed. NOTE: process in
increasing plane number.
IN2NAME.....The dirty beam image name. blank => actual
INNAME, otherwise standard defaults.
The real and imaginary parts of the dirty beam
must have names 'QBM001' and 'UBM001' respectively.
IN2SEQ......The dirty beam image sequence number. 0 => actual
INSEQ
IN2DISK.....The dirty beam image disk drive no. 0 => any
OUTNAME.....The clean map image name. blank => Standard
defaults based on INNAME.
The real and imaginary parts of the input image
will have names 'QCL001' and 'UCL001' respectively.
OUTSEQ......The clean map image seq. no., 0=> highest unique
If >0; image will be created if new,
overwritten if image name exists.
OUTDISK.....Clean Map disk drive no., 0=> highest with space
INVERS......The CX file version number. 0=> highest
current one. -1 => create new one. If none
exist, one will be created in any case.
GAIN........The CLEAN loop gain. 0 => 0.10
FLUX........Stop CLEAN when abs(resid. image max in CLEAN
window) < FLUX (Jy).
NITER.......CLEAN iteration limit. 0 => 200
If <0 then the CLEAN will stop at the first
negative component or ABS (NITER) whichever is
encountered first.
BMAJ........The FWHM (asec) major axis of the restoring beam.
The parameters of the restoring beam MUST be
provided unless you want a residual image. Set
BMAJ <= 0 for a residual image.
BMIN........The FWHM (asec) minor axis of the restoring beam.
BPA.........The position angle in the unrotated image of BMAJ.
NBOXES......Number (<=50) of rectangular search boxes. 0 => 1
CLBOX.......A 4x50 array with the BLC and TRC of each box.
0 => use inner quarter of input map (first box)
0 => ignore box (boxes 2 - 50)
BADDISK.....This array contains the numbers of disks on which
it is desired that scratch files not be located.
BADDISK has no effect on input and output maps.
