Detailed Description

VisibilityIterator2 iterates through one or more readonly MeasurementSets.

Intended use:

Public interface

Review Status

Date Reviewed:: yyyy/mm/dd

Prerequisite

Etymology

The VisibilityIterator2 is a readonly iterator returning visibilities

Synopsis

VisibilityIterator2 provides iteration with various sort orders for one or more MSs. It has member functions to retrieve the fields commonly needed in synthesis calibration and imaging.

One should use VisBuffer to access chunks of data.

Example

Motivation

For imaging and calibration you need to access an MS in some consistent order (by field, spectralwindow, time interval etc.). This class provides that access.

Thrown Exceptions

To Do

cleanup the currently dual interface for visibilities and flags
sort out what to do with weights when interpolating

+-------------------+ | | | Writeback Methods | | | +-------------------+

This method writes back any changed (dirty) components of the provided VisBuffer and is the preferred method for writing data out.

Reimplemented from casa::vi::TransformingVi2.

void casa::vi::FinalTvi2::writeDataValues	(	MeasurementSet &	ms,
		const RefRows &	rows
	)		`[protected]`

virtual void casa::vi::FinalTvi2::writeFlag ( const Matrix< Bool > & flag ) [virtual]

Write/modify the flags in the data.

This will flag all channels in the original data that contributed to the output channel in the case of channel averaging. All polarizations have the same flag value.

Reimplemented from casa::vi::TransformingVi2.

virtual void casa::vi::FinalTvi2::writeFlag ( const Cube< Bool > & flag ) [virtual]

Write/modify the flags in the data.

This writes the flags as found in the MS, Cube (npol,nchan,nrow), where nrow is the number of rows in the current iteration (given by nRow ()).

Reimplemented from casa::vi::TransformingVi2.

virtual void casa::vi::FinalTvi2::writeFlagCategory ( const Array< Bool > & fc ) [virtual]

Reimplemented from casa::vi::TransformingVi2.

virtual void casa::vi::FinalTvi2::writeFlagRow ( const Vector< Bool > & rowflags ) [virtual]

Write/modify the flag row column; dimension Vector (nrow)

Reimplemented from casa::vi::TransformingVi2.

void casa::vi::FinalTvi2::writeKeyValues	(	MeasurementSet &	ms,
		const RefRows &	rows
	)		`[protected]`

void casa::vi::FinalTvi2::writeMiscellaneousValues	(	MeasurementSet &	ms,

virtual void casa::vi::FinalTvi2::writeModel	(	const RecordInterface &	rec,
		Bool	iscomponentlist = `True`,
		Bool	incremental = `False`
	)		`[virtual]`

Write the information needed to generate on-the-fly model visibilities.

Reimplemented from casa::vi::TransformingVi2.

virtual void casa::vi::FinalTvi2::writeSigma ( const Vector< Float > & sig ) [virtual]

Write/modify the Sigma.

virtual void casa::vi::FinalTvi2::writeSigmaMat ( const Matrix< Float > & sigmat ) [virtual]

Write/modify the ncorr x nrow SigmaMat.

virtual void casa::vi::FinalTvi2::writeVisCorrected ( const Cube< Complex > & vis ) [virtual]

Write/modify the visibilities.

This is possibly only for a 'reference' MS which has a new DATA column. The first axis of the matrix should equal the selected number of channels in the original MS. If the MS does not contain all polarizations, only the parallel hand polarizations are used. virtual void writeVisCorrected (const Matrix<CStokesVector> & visibilityStokes); virtual void writeVisModel (const Matrix<CStokesVector> & visibilityStokes); virtual void writeVisObserved (const Matrix<CStokesVector> & visibilityStokes);

Write/modify the visibilities This writes the data as found in the MS, Cube (npol,nchan,nrow).
