Member Function Documentation

void casa::StatWt::_constructVi ( std::shared_ptr< vi::VisibilityIterator2 > &  vi, std::shared_ptr< vi::StatWtTVILayerFactory > &  factory  ) const

private

Construct the iterator.

void casa::StatWt::setCombine

(

const casacore::String &

combine

)

set columns for which to ignore changes when aggregating data

void casa::StatWt::setOutputMS

(

const casacore::String &

outname

)

void casa::StatWt::setPreview

(

casacore::Bool

preview

)

set preview mode (True) or not (False)

void casa::StatWt::setTimeBinWidth

(

const casacore::Quantity &

binWidth

)

void casa::StatWt::setTimeBinWidth

(

casacore::Double

binWidth

)

binWidth must be in seconds

void casa::StatWt::setTimeBinWidthUsingInterval

(

casacore::uInt

n

)

set the time bin width using an integral number of integration time.

For this purpose, the integration time is defined as the median value of the INTERVAL column. If either extrema in this column is more than 25% different from the median, an exception will be thrown because there is no single representative value of the integration time.

void casa::StatWt::setTVIConfig

(

const casacore::Record &

config

)

set the StatWtTVI config record

casacore::Record casa::StatWt::writeWeights

(

)
