HELP SECTION
MFPRT
Type: Task
Use: MFPRT prints on the line printer or terminal the rows of an MF
extension file. If the line width is too small to hold all
columns, it will print as many as it can and then loop back to
the beginning to print the next set of columns. OPTYPE='STAR'
and OPTYPE='STDE' print in the format used by task STARS to
make an ST file to appear on image plots. OPTYPE='LIST' allows
you to print an MF table in the special format used for source
lists by such tasks as SETFC, FACES, and BOXES. The angular
units are degrees, arc seconds, or milli arc seconds, depending
on the cell size. The flux scale is Jy or milliJy or even
microJy as needed.
Adverbs:
INNAME.....Image name (name). Standard defaults.
INCLASS....Image name (class). Standard defaults.
INSEQ......Image name (seq. #). 0 => highest.
INDISK.....Disk drive # of image. 0 => any.
INVERS.....First MF extension to list. 0 => 1.
Enables the user to run through all available MF tables
attached to a given file and list the values in one output
file.
IN2VER.....Last MF extension to list < INVERS => to end.
XINC.......Increment between MF extension files. <= 0 => 1.
DOCRT......False (<= 0) use the line printer if OUTPRINT = ' '
else write named OUTPRINT file only.
When OUTPRINT is not blank, DOCRT=-2 suppresses the
page-feed character on page headers and DOCRT=-3
suppresses page headers and most other header
information. When OUTPRINT is blank, the line
printer will be used. MFPRT now counts the lines
to be printed before printing any and asks for
permission to continue if the count > 500.
True (> 0) use the terminal interactively. The task will
use the actual terminal width as a display limit
unless 72 < DOCRT < width. In that case, the display
limit will be DOCRT characters.
OUTPRINT...Disk file name in which to save the line printer output.
' ' => use scratch and print immediately for interactive
jobs - batch jobs use OUTPRINT = 'PRTFIL:BATCHjjj.nnn'
(jjj= job #, nnn = user #). When OUTPRINT is not blank,
multiple outputs are concatenated, and the file is not
actually printed.
FLUX.......Flux level below which to ignore components. The column
used is the total flux in I polarization, column 3.
0 => accept all components.
IMSIZE.....Minumum and maximum size allowed for components in arc
seconds. IMSIZE(2) <= 0 => accept all components. If not
given, then large, non-physical components may slip
through. The columns tested are the fit major and minor
axis sizes, columns, 6 and 7.
SORT.......Sort order to use: 'C', 'F', 'T', 'X', 'Y', 'J', 'N', 'P'
for channel, peak flux, total flux, X position, Y
position, major axis, minor axis, position angle. Use
'-C' etc for inverse order. ' ' => '-F'
OPTYPE.....' ' yields two different outputs depending on whether
the data have multiple spectral channels. The multi-
channel one may be forced with OPTYPE='LINE' and the
continuum one may be forced with OPTYPE='CONT'.
'USER' prints the columns specified in BOX like PRTAB but
with more appropriate units. See EXPLAIN for details.
'LIST' causes the output to be in the format used by
SETFC, BOXES and other tasks reading source lists.
These tasks expect the flux column to be in milliJy
but MFPRT may use microJy if the source total fluxes
are all less than 1 Jy and the lowest included flux is
less than 1 milliJy. The source diameter column is
the sqrt(Bmaj*Bmin) in arc sec and the format is
RA,Dec,Flux,Width as F9.5,1X,F9.5,I7,F10.4.
'LIDE' as 'LIST' but using deconvolved widths
'STAR' causes the output to be in the format used by
STARS: Ra, Dec (in sexagesimal), Major, Minor, PA,
Type, label. Size is fit size.
'STDE' causes the output to be in the format used by
STARS: Ra, Dec (in sexagesimal), Major, Minor, PA,
Type, label. Size is deconvolved size.
DOHMS......> 0 => give full source positions in sexagesimal format
<=0 => give source positions as offsets from the
reference in asec if DOHMS <= -1.5 otherwise in
degrees - for OPTYPE='STAR' DOHMS = -1 produces RA
and DEC in decimal degrees while -2 produces
offsets in arcsec
(not used in LIST, for OPTYPE 'STAR' task STARS can use
all values of DOHMS = 1, -1, and -2 -> set DECIMAL = 0, 1,
2, resp. in STARS)
FORMAT.....= -1 => omit row numbers. Otherwise all OPTYPEs except
'LIST', 'LIDE', 'STAR', and 'STDE' will print the
(sorted) row number with each row.
DOALL......= 1 or 3 scale Peaks and fluxes for primary beam
correction stored in MF table
= 2 or 3 scale Peaks for bandwidth smearing correction
stored in table
CLEV.......> 0 => ('STAR', 'STDE' only) scale source sizes by total
flux divided by CLEV.
<=0 => ('STAR', 'STDE' only) no scaling of source size
SYMBOL.....Symbol type used for sources ('STAR' only)
1: Plus sign 12: Five pointed star
2: Cross (X) 13: Star of David
3: Circle 14: Seven-pointed star
4: Box 15: Eight-pointed star
5: Triangle 16: Nine-pointed star
6: Diamond 17: Ten-pointed star
7: Pentagon 18: 11-pointed star
8: Hexagon 19: 12-pointed star
9: Septagon 20: 13-pointed star
10: Octagon 21: 14-pointed star
11: Nine-gon 22: Cross (X) with gap
23: Vertical line
If SYMBOL < 0, then the symbol used is
flux/(-SYMBOL) + 1
BOX........To select the column numbers to be printed including their
order. Up to 40 may be selected. 0 => all columns in
basic order.
