Description

Prerequisite

Etymology

GJonesPoly describes the electronic gain visibility Jones matrix parametrized as a polynomial over time.

Synopsis

See VisEquation for definition of the Visibility Measurement Equation.

The elements of GJonesSpline are only non-zero on the diagonal.

Motivation

Support electronic gain calibration using polynomials over time.
