DOBLANK
Type: Adverb (Logical, > 0 => true)
Use: To control the handling of blanking and/or blanked pixels.
The actual meaning depends on the task (see below).
Null value: 0 false
Tasks:
BPPLT....Plots selected contents of bandpass (BP) files versus time.
CHKFC....Makes images of Clean boxes from Boxfile. DOBLANK > 0
causes magic blanks to be written outside Clean boxes.
CLCAL....Merges and smooths SN tables, applies them to CL tables.
DOBLANK controls how blanked (failed) solutions are
handled.
CLSMO....Smooths a calibration CL table. DOBLANK controls whether
good or failed solutions are the ones changed.
CONVL....Convolves an image with a gaussian or another image.
DOBLANK > 0 causes the smoothed output to be blanked at
those pixels which were blanked on input.
ELFIT....Plots/fits selected contents of SN, TY, SY, PC or CL files.
DOBLANK > 0 controls the plot symbol used for blanked data,
otherwise they are omitted.
KNTR.....Make a contour/grey plot file from an image w multiple
panels. DOBLANK > 0 causes the boundary between blanked and
normal pixels to be plotted.
MASKS....Makes mask image of Clean boxes from boxfile. DOBLANK > 0
cuses the pixels outside of Clean boxes to be magic blanks.
SNBLP....Plots selected contents of SN or CL files on a baseline
basis. DOBLANK > 0 selects the plot symbol for blanked
data which are otherwise omitted.
SNFIT....Fits parabola to SN amplitudes and plots result. DOBLANK>0
selects the plot symbol for blanked data which are otherwise
omitted.
SNIFS....Plots selected contents of SN, TY, SY, PC or CL files by
IF. DOBLANK > 0 selects the plot symbol for blanked data
which are otherwise omitted.
SNPLT....Plots selected contents of SN, SY, TY, PC or CL files versus
time. DOBLANK > 0 selects the plot symbol for blanked data
which are otherwise omitted.
SNSMO....Smooths and filters a calibration SN table. DOBLANK
controls whther good or blanked solutions (or both) are
changed.
SPCOR....Task to correct an image for a primary beam and spectral
index. DOBLANK > 0 causes the output to be blanked where
the spectral index image is blanked. Else output is the
beam corrected input with no spectral index alteration.
SYVSN....Plots selected SY/TY data with SN solution values versus
time. DOBLANK > 0 controls the plt symbol used for blanked
data which are otherwise omitted.
TYSMO....Smooths and filters a calibration TY or SY table. DOBLANK
controls whether blanked or good data or both are changed.
UNSPX....Removes spectral index model from a data cube. DOBLANK
controls whether blanked pixels in the model blank the
output.
UVHIM....Makes image of the histogram on two user-chosen axes.
DOBLANK > 0 causes all 0 values to be written with magic
blanks.
