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. Plot tasks: 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 vectors. PROFL...Makes plot file of image profiles. Other tasks: 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. ----------------------------------------------------------------
