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. 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. ----------------------------------------------------------------
