AIPS HELP file for STFACTOR in 31DEC18
As of Mon Jun 18 14:55:31 2018
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 plotted.
Null value: 0 => no plot.
CNTR....Makes plot file of image contours.
GREYS...Makes plot file of image grey-scale plus contours.
KNTR....Makes plot file of multiple planes of image contours.
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 GAIN.
