The user can specify the minimum flux level that is required in the CC file to be used in CALIB. He/she can then also edit the CC file to remove components outside a specified area. After the CC file has been edited, CALIB is run using the new CC file and then MX. The resulting image is plotted and sent to the Postscript printer. Before attempting to run HYB the user must first define the procedure. This is done by typing: >RUN HYB and only needs to be done once. The user can them examine the inputs to the HYB procedure by typing: >INP HYB To run a hybrid mapping loop type: >HYBRID minimum flux level that is required in the CC file to be used in CALIB. He/she can then also edit the CC file to remove components outside a specified area. After the CC file has been edited, CALIB is run using the new CC file and then MX. The resulting image is plotted and sent to the Postscript printer. Before attempting to run HYB the user must first define the procedure.

The user can them examine the inputs to the HYB procedure by typing: >INP HYB To run a hybrid mapping loop type: >HYBRID Adverbs: ===== INPUT MAP ============= INNAME......Input Clean map name (name). Standard defaults INCLASS.....Input Clean map name (class). Standard defaults INSEQ.......Input Clean map name (seq. #). 0 => highest INDISK......Input Clean map disk drive #. 0 => any INVER.......CC file version #. 0 => highest ===== CLEAN COMPONENT EDITING NCCBOX......The number of editing boxes on the CCBOX array (<10) CCBOX.......An array defining the boxes to include Clean components. The numbers are bottom left corner (X,Y) and top righ corner (X,Y) but are in arcseconds not pixels. CUTOFF......Minimum merged flux. Use a large negative value of no edits. 0.0 cuts of at zero. ===== Input UV data ========= IN3NAME.....UV file name (name). Standard defaults IN3CLASS....UV file name (class). Standard defaults IN3SEQ......UV file name (seq. #). 0 => highest IN3DISK.....UV file disk unit #. 0 => any ===== Output UV data ========= OUTNAME.....UV file name (name). Standard defaults OUTSEQ......UV file name (seq. #). 0 => highest ===== CALIB ================= REFANT......Reference antenna for phases. 0 => CALIB will choose SOLINT......Solution interval (min). SOLMODE.....' ','P','A&P','P!A','GCON' 'A&P ' => amplitude and phase. 'P ' => phase only 'P!A ' => phase only (no amplitude information) 'GCON' => amplitude and phase with constraints on amplitude. This mode requires setting SOLTYPE='GCON', uses GAINERR and SOLCON may be used. ' ' => 'A&P ' for multisource (raw) data, => 'P ' for single source data. SOLTYPE......' ','L1','GCON' ' ' => normal least squares, 'L1 ' => L1 solution, 'GCON' => least squares which may include gain constraint. UVRANGE......uv range for full wt. (klambda) WTUV.........wt for points outside range MINANT.......Minimum number of antennas. 0 => 6 PRTLEV.......Print level. MINSNR.......Min. SNR for solution (0=>5) ===== MX ==================== CELLSIZE.....(X,Y) size of grid in asec. IMSIZE.......Image size (pixels). RASHIFT......RA shift (asec) DECSHIFT.....DEC shift (asec) NBOXES.......Number of boxes for CLEAN CLBOX........Four coordinates for each box UVTAPER......(U,V) taper (klambda) MXUVR........UVRANGE for MX Min & Max baseline (klambda) UVWTFN.......Weighting function (' ','NA') ZEROSP.......Zero spacing fluxes. NITER........Number of CLEAN iterations. BMAJ.........Beam major axis (arcsec). BMIN.........Beam minor axis (arcsec). BPA..........Beam position angle (deg). ===== PLOTTING ============== BLC..........Lower left corner of plot TRC..........Upper right corner of plot CLEV.........Lowest contour level. Logarithmic contours with 7 per decade will be used ===== GENERAL =============== BADDISK......Disks to avoid. ----------------------------------------------------------------
