virtual Bool solve(VisEquation& ve) = 0

virtual VisBuffer& apply(VisBuffer& vb) = 0

virtual VisBuffer& applyInv(VisBuffer& vb) = 0

Description

Prerequisite

Etymology

ACoh describes an interface for additive errors to be used in the VisEquation. It is an Abstract Base Class: most methods must be defined in derived classes.

Synopsis

See VisEquation for definition of the Visibility Measurement Equation.

The following examples illustrate how an ACoh can be used:

Simulation: random additive noise of a certain scaling can be added: SimACoh
Correlator offsets

Example

      // Read the VisSet from disk
      VisSet vs("3c84.MS");

      VisEquation ve(vs);

      // Make an ACoh
      CorrelatorOffsetACoh coac(vs);

      ve.setACoh(coac);

      // Correct the visset
      ve.correct();

Motivation

The properties of an additive component must be described for the VisEquation.

To Do
