Type: Adverb (Real)
Use: A multiplication factor. In plot tasks, it is used to scale the
plotting of symbols for objects from an ST (stars) table. If
STFACTOR = 0, no symbols are plotted. If STFACTOR not = 0, the
symbol sizes (in arc sec) in the file are scaled by abs(STFACTOR)
and plotted. If STFACTOR < 0, any labels in the file are also
Null value: 0 => no plot of ST contents
CCNTR....Generate a contour plot file from an image and CC table.
CNTR.....Generate a contour plot file or TV plot from an image.
GREYS....Makes plot file of image grey-scale plus contours.
KNTR.....Make a contour/grey plot file from an image w multiple
PCNTR....Makes plot file of image contours and polarization
PROFL....Makes plot file of image profiles.
SDCLN...Does image deconvolution using the Clark CLEAN algorithm
followed by a modified Steer-Dewdney-Ito CLEAN. STFACTOR is
the loop gain (fraction of each pixel's flux taken as a
component flux) during the SDI phase of the deconvolution. It
must be <= the default. 0 => lower of 0.9 * (1-CUTOFF) and
COSTAR...Verb to plot a symbol at given position on top of a TV
image. Symbol is 2 * STFACTOR pixels in radius.
TVSTAR...Verb to plot star positions on top of a TV image. STFACTOR
used as with plot tasks.
