Detailed Description

Class to handle lookup or indexing into an MS POLARIZATION subtable.

Prerequisite

• MeasurementSet
• MSPolarization

Etymology

From "MeasurementSet", "POLARIZATION subtable" and "index".

Synopsis

This class provides lookup and indexing into an MS POLARIZATION subtable. These services include returning rows numbers (which for the POLARIZATION subtable are POLARIZATION_ID's) associated with specific data in the subtable.

Example

Motivation

Collect together all subtable indexing and lookup for the POLARIZATION subtable, for encapsulation and efficiency.
