Detailed Description

VisibilityIterator2 iterates through one or more readonly MeasurementSets.

Intended use:

Public interface

Review Status

Date Reviewed:

yyyy/mm/dd

Prerequisite

• MSIter
• casacore::MeasurementSet
• VisSet

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 casacore::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

Write/modify the visibilities.

This is possibly only for a 'reference' casacore::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 casacore::MS does not contain all polarizations, only the parallel hand polarizations are used. virtual void writeVisCorrected (const casacore::Matrix<CStokesVector> & visibilityStokes); virtual void writeVisModel (const casacore::Matrix<CStokesVector> & visibilityStokes); virtual void writeVisObserved (const casacore::Matrix<CStokesVector> & visibilityStokes);

jagonzal (to be reviewed by jjacobs): I need to set inputVii_p to NULL from MSTransformIterator destructor because MSTransformIteratorFactory is borrowing the ViImplementation2 from the input iterator, which is deleted in the first steps of the MSTransformIterator destructor.
