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
Procedures:
VLACLCAL...Runs CLCAL and prints the results with LISTR.
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
causes 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.
