Constructor & Destructor Documentation

casa::VisSet::VisSet ( )

inline

default constructor, only useful to assign to later.

Definition at line 106 of file VisSet.h.

casa::VisSet::VisSet	(	casacore::MeasurementSet &	ms,
		const casacore::Block< casacore::Int > &	columns,
		const casacore::Matrix< casacore::Int > &	chanSelection,
		casacore::Double	timeInterval = `0`,
		casacore::Bool	compress = `false`,
		casacore::Bool	doModelData = `true`
	)

Construct from a casacore::MeasurementSet, with iteration order specified in columns (giving the casacore::MS enum for the column) Specify channel selection as a casacore::Matrix(3,nSpw) where for each spectral window the three values are start,nChannel and spectral window number.

Spectral windows without an entry will have all channels selected. Specify a time interval for iterating in 'chunks' of time. The default time interval of 0 groups all times together. This constructor creates two new columns: MODEL_DATA and CORRECTED_DATA If they already exist and have the same channel selection applied, they are reused. Note that the contents of these columns are NOT initialized, you should fill them before trying to read the data. The casacore::MS calibration scratch columns can be optionally compressed.

casa::VisSet::VisSet	(	casacore::MeasurementSet &	ms,
		const casacore::Block< casacore::Int > &	columns,
		const casacore::Matrix< casacore::Int > &	chanSelection,
		casacore::Bool	addScratch,
		casacore::Double	timeInterval = `0`,
		casacore::Bool	compress = `false`,
		casacore::Bool	doModelData = `true`
	)

Same as above, but provide scratch column option.

casa::VisSet::VisSet	(	casacore::Block< casacore::MeasurementSet > &	mss,
		const casacore::Block< casacore::Int > &	columns,
		const casacore::Block< casacore::Matrix< casacore::Int > > &	chanSelections,
		casacore::Bool	addStratch = `false`,
		casacore::Double	timeInterval = `0`,
		casacore::Bool	compress = `false`,
		casacore::Bool	doModelData = `true`
	)

This is a constructor for multiple MS...but everything is same as the one above.

casa::VisSet::VisSet	(	casacore::MeasurementSet &	ms,
		const casacore::Matrix< casacore::Int > &	chanSelection,
		casacore::Double	timeInterval = `0`
	)

This is a no frills constructor, no re-sorting, the default order is used, no scratch columns is made even if they don't exist.

So if you use this constructor and plan to use the scratch columns make sure that they exist prior to constructing the VisSet this way.

casa::VisSet::VisSet ( ROVisibilityIterator & vi )

Constructor from visibility iterator....a temporary fix as EPJones as Imager stops using VisSet.

casa::VisSet::VisSet	(	const VisSet &	vs,
		const casacore::Block< casacore::Int > &	columns,
		casacore::Double	timeInterval = `0`
	)

Construct from an existing VisSet, this references the underlying casacore::MeasurementSet(s) but allows a new iteration order and time interval to be specified.

casa::VisSet::~VisSet ( )

Destructor, flushes the data to disk.

	)

Re-initialize the VisibilityIterator (cf copy ctor)

void casa::VisSet::selectAllChans ( )

Set nominal selection to ALL channels.

void casa::VisSet::selectChannel	(	casacore::Int	nGroup,
		casacore::Int	start,
		casacore::Int	width,
		casacore::Int	increment,
		casacore::Int	spectralWindow
	)

Reset the channel selection.

Only subsets of the original selection (set in constructor) can be specified. Note: this calls origin on the iterator.

void casa::VisSet::selectChannel	(	casacore::Int	nGroup,
		casacore::Int	start,
		casacore::Int	width,
		casacore::Int	increment,
		casacore::Int	spectralWindow,
