uvcoher - Copy and average a uv dataset.
UVCOHER performs time averaging,and reports on the measured
coherence in the selected line=
Coherence is defined as the ratio between the amplitude of
vector average and the average scalar amplitude. This number
should be 1 for perfect noiseless data and 0 for uncorrelated
Currently it prints out a simple table,

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).
NOTE; This program requires you to select 1 channel.
If a value is given, uvcoher 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 10.
Note: No time averaging makes no sense in this program
This gives extra processing options. Several options can be given,
each separated by commas. They may be abbreviated to the minimum
needed to avoid ambiguity. Possible options are:
nocal Do not apply the gains file. By default, UVCOHER
applies the gains file in copying the data.
nopass Do not apply bandpass corrections. By default,
UVCOHER corrects for the bandpass shape if the
required information is available.
nopol Do not apply polarizatiopn corrections. By default
UVCOHER corrects for polarization corss-talk.
relax Normally UVCOHER discards a correlation record if
all the correlations are bad. This option causes
UVCOHER to retain all records.
