HELP SECTION
HYB (RCW, modified by PJD)
Procedure: This procedure will run a hybrid mapping loop (CALIB + MX)
after first editing the CC file. 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

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.
