AIPS HELP file for PCUT in 31DEC22
As of Mon Jun 27 4:46:57 2022
Type: Adverb (Real)
Use: If some value is below PCUT in units of the image, then
some action will not occur.
Null value: none and no default.
KNTR..........Make a contour/grey plot file from an image w multiple
panels. Total polarizations less than PCUT (Jy/beam)
do not generate plotted vectors.
PCNTR.........Generate plot file with contours plus polarization
vectors. PCUT causes vectors to be omitted based on
the intensity of the vector-length (total polarization)
POLCO.........Task to correct polarization maps for Ricean bias.
Polarizations less than PCUT (sigma, i.e., units of the
noise) are blanked on output.
QUFIX.........Determines Right minus Left phase difference, corrects
cal files. Only total polarizations greater than PCUT
i n both images are used.
RMFIT.........Fits 1-dimensional polarization spectrum to Q/U cube.
Fits are done only to spectra having an average total
polarization greater than PCUT. May be changed on a
