class	VisibilityIterator2

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
