Basic Information on gpcopy
Purpose: Copy or merge gains, bandpass and polarization correction.
GpCopy is a MIRIAD task which copies or merges calibration corrections
(antenna gains, polarization leakages, frequency table, bandpass item)
from one data-set to another.
The name of the input data-set. This will normally be a visibility
data-set. No default.
The name of the output data-set. This is NOT created by GPCOPY, but
rather the relevant items are copied to this data-set.
This determines how the calibration tables, etc, are ``copied''
to the output. The default is to ``copy''. Possible values are:
create Create the output, and copy the calibration tables to it.
copy Copy the calibration tables to the output, overwriting
and previously existing calibration tables. This is the
apply Apply the input calibration tables to the output calibration
tables. This is the sort of operation that you might do
if you have two sets of calibration tables that you wish
to "multiply" together (implemented for gains and bandpass
merge Merge the two calibration tables together. This is the
sort of operation that you will want to perform if you
have two sets of calibration tables which are disjoint in
time (e.g. you used two secondary calibrators). The
merge opertation will weave the two sets of tables together.
(implemented for gain tables only).
This gives extra processing options, which are used to suppress
the copying of certain items. Several options can be given,
separated by commands. Minimum match is used:
nopol Do not copy the items dealing with polarization
nocal Do not copy the items dealing with antenna gain
nopass Do not copy the items dealing with bandpass
calibration (this includes the cgains and wgains tables).
relax Relax the interpolation interval limits to 0.5 days.
Use this when copying gain tables created by selfcal
or gpscal to other sources.
With mode=apply: simply adjust the existing output gains,
rather than doing the default merge & multiply of solutions.
