NAME

smarewt - Copy a uv dataset, re-weighting the visibility.  

PERSON RESPONSIBLE

jhz  

CATEGORIES

uv analysis  

DESCRIPTION

SmaReWt copies a uv dataset, calculating the mean values of antenna gains in amplitude and multiplying the visibility variances by the mean antenna gains. The re-scaled visibility variances can be used as the weights in the imaging process.  

PARAMETERS

vis
The name of the input uv data sets. Several can be given (wild cards are supported). No default.
gain
The name of a uvdata with a gain table based on which, the visibility data are re-weighted.
select
The normal uv selection commands. The default is copy everything.
line
The normal uv linetype in the form:
  line,nchan,start,width,step
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).
options
This gives extra processing options.
   scalar    Means do scalar averaging for the amplitude of gains.
             This is the default. 
   vector    Means do vector averaging for the amplitude of gains.
   report    Means printing the mean antenna-based gains.
out
The name of the output uv data set. No default.
