Detailed Description

CalInterpolator: a class to interpolate calibration information.

Intended use:

Part of API

Prerequisite

• CalTable module
• CalInterpolation module
• VisBuffer module

Etymology

From "calibration" and "interpolation".

Synopsis

This base class defines the interface for calibration interpolation. Specializations for calibration table and calibration model interpolation are provided through inheritance. Calibration table solutions may be discretely sampled values for parametrized solutions and interpolation of both is supported through inherited sub-types. Calibration models may be analytic (e.g. parallactic angle PJones) or empirical based on global or other data not stored in calibration tables (e.g. empirical ionosphere models).

Example

Motivation

Define the base class interface for different calibration interpolation types.

To Do

i) None known.
