Printer disk file to save
Use: The image intensities stored in the memory of the TV
display are translated by 2 "look-up-tables" in
succession. The first is used by AIPS mostly for
simple linear black-and-white enhancements (TVTRANSF)
and is called the LUT. The second is used to apply
the gamma correction (see GAMMASET) and to display
pseudo coloring (TVPSEUDO) of the image and is called
the OFM ("output function memory"). OFMLIST prints
the OFM table for one color when they are all the same
(black and white display) or for all three colors.
The number of input intensity values (output from the
LUT) depends on the type of TV. It is 1024 on IIS
models 70 and 75 and 256 on DeAnza, IIS IVAS, and the
SUN Screen Server. The output values are scaled to
numbers between 0 and 10000.
DOCRT......False (<= 0) use the line printer if OUTPRINT = ' '
else write named OUTPRINT file only.
With the file, DOCRT=-2 suppresses the page-feed
character in the header lines. DOCRT=-3 suppresses
the header lines except at the start.
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
