Basic Information on uvaver
Purpose: Copy and average a uv dataset.
Categories: uv analysis
UVAVER copies a uv dataset, performing averaging, both in time
The name of the input uv data sets. Several can be given (wild
cards are supported). No default.
The normal uv selection commands. The default is copy everything.
The normal uv linetype in the form:
The default is all channels (or all wide channels if there are no
spectral channels). The output will consist of only spectral or
wideband data (but not both).
The normal reference linetype, in the form:
The default is no reference line.
If a value is given, uvaver converts the input into the required
polarizations before writing to the output. Default is to copy
across the polarizations present in the input files.
Time averaging interval, in minutes. The default is 0 (i.e. no
This gives extra processing options. Several options can be given,
each separated by commas. They may be abbreivated to the minimum
needed to avoid ambiguity. Possible options are:
nocal Do not apply the gains file. By default, UVAVER
applies the gains file in copying the data.
nopass Do not apply bandpass corrections. By default,
UVAVER corrects for the bandpass shape if the
required information is available.
nopol Do not apply polarizatiopn corrections. By default
UVAVER corrects for polarization corss-talk.
relax Normally UVAVER discards a correlation record if
all the correlations are bad. This option causes
UVAVER to retain all records.
vector Means do vector averaging. This is the default.
scalar Means do scalar averaging for the amplitudes
and vector averaging for the phase.
scavec Means do scalar averaging for the amplitudes of
the `parallel-hand' polarisations (i,xx,yy,rr,ll).
Vector averaging is used for the amplitudes of
the cross-hand visibilities (q,u,v,xy,yx,rl,lr)
and for the phases for all visibilities.
The name of the output uv data set. No default.
