Detailed Description

CalIntpMatch: a class to hold calibration interpolation index maps.

Intended use:

Public interface

Prerequisite

MSCalEnums module
VisBuffer module
CalMainBuffer module
casacore::MSSelection module

Etymology

From "calibration", "interpolation index" and "match".

Synopsis

The CalIntpMatch class holds calibration interpolation index maps. These define which subset of calibration table rows are associated with any given visibility row, i.e. which data and calibration indices need to match in selecting calibration for a given visibility record. The map type is defined in terms of an enumerated set of possibilities, including for example, requiring an exact match between the antenna and spectral window id.'s. The most general interpolation map is defined by a matching set of synthesis selections (as defined matchIndex() and calRows() which determine, for associated calibration and visibility buffers, the calibration row mapping for a given visibility.

Example

Motivation

Encapsulate match operations for calibration and visibility data indices.
