CUTOFF
Type: Adverb (Real)
Use: If some value is below CUTOFF in units of the data, then some
action will not occur.
Null value: none and no default.
Tasks:
BPPLT.......Plots selected contents of bandpass (BP) files versus time.
CCEDT.......Select CC components in BOXes and above mininum flux.
Clean components below CUTOFF Jy are rejected.
CCNTR.......Generate a contour plot file from an image. Clean
components below CUTOFF are not plotted.
CCSEL.......Select significant CC components. Regions with summed
Clean flux below CUTOFF are omitted from the output.
CLCAL.......Merges and smooths SN tables, applies them to CL tables.
CUTOFF is the maximum time interval over which
interpolation will take place.
CLSMO.......Smooths a calibration CL table. CUTOFF is the minimum
summed weight from the smoothing function.
CLVLB.......Corrects CL table gains for pointing offsets in VLBI
data. CUTOFF is the minimum single-dish beam value
allowed.
ELFIT.......Plots/fits selected contents of SN, TY, SY, PC or CL
files. CUTOFF is the minimum table weight for plotted
points.
EVASN.......Evaluates statistics in SN/CL tables. CUTOFF is the
minimum table weight for points to be considered.
FIXAL.......Least squares fit aliasing function and remove. CUTOFF
is the maximum allowed RMS of the residual.
PCCOR.......Corrects phases using PCAL tones data from PC table.
CUTOFF may be used to turn off the cable correction.
PCFIT.......Finds delays and phases using a pulse-cal (PC) table.
CUTOFF is the maximim delay change in nanosec before a
discontinuity is introduced.
RIRMS.......Computes rms of real/imag of a selected subset of a uv
data set
SDCLN.......Does image deconvolution with BGC CLEAN and/or
Steer-Dewdney-Ito methods. CUTOFF is the intensity
(fraction) above which a pixel is taken as an SDI
component.
SDLSF.......Least squares fit to channels and subtracts from SD uv
data. CUTOFF is the maximum allowed rms of the residual
before the data are flagged.
SNBLP.......Plots selected contents of SN or CL files on a baseline
basis. Table weights below CUTOFF will not be plotted.
SNFIT.......Fits parabola to SN amplitudes and plots result. Table
entries with weights below CUTOFF are not used.
SNFLG.......Writes flagging info based on the contents of SN files.
Table entries with weight below CUTOFF are not used.
SNIFS.......Plots selected contents of SN, TY, SY, PC or CL files by
IF. Table entries with weight below CUTOFF are not
plotted.
SNPLT.......Plots selected contents of SN, SY, TY, PC or CL files
versus time. Table entries with weight below CUTOFF are
not plotted.
SNRMS.......Print statistics for selected contents of SN, SY, TY,
PC or CL files.
SNSMO.......Smooths and filters a calibration SN table. CUTOFF is
the minimum summed weight from the smoothing function.
SYSOL.......Undoes and re-does nominal sensitivity application for
Solar data. If fraction of good SY values < CUTOFF,
apply an average correction instead.
SYVSN.......Plots selected SY/TY data with SN solution values versus
time. Table entries with weight below CUTOFF are not
plotted.
TYAPL.......Undoes and re-does nominal sensitivity application. If
fraction of good SY values < CUTOFF, apply an average
correction instead.
TYSMO.......Smooths and filters a calibration TY or SY table. CUTOFF
is the minimum summed weight from the smoothing function.
UVLSD.......Least squares fit to channels and divides the uv data.
Solution is flagged if the rms residual in the fit
channels exceeds CUTOFF.
UVLSF.......Least squares fit to channels and subtracts from uv data.
Solution is flagged if the rms residual in the fit
channels exceeds CUTOFF.
Procedures:
DOOSRO......Calibrating amplitude and phase, and imaging VLA data.
CUTOFF is the minimum component flux in Cleaning.
PIPEAIPS....Calibrating amplitude and phase, and imaging VLA data.
CUTOFF is the minimum component flux in Cleaning.
VLARUN......Calibrating amplitude and phase, and imaging VLA data.
CUTOFF is the minimum component flux in Cleaning.
