Description

Prerequisite

Etymology

SimVisJones describes random multiplicative gains to be used in the VisEquation.

Synopsis

See VisEquation for definition of the Visibility Measurement Equation. See VisJones for how SimVisJones is to be used.

Motivation

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

To Do

Member Description

enum Distribution

Two supported distributions for the simulated gain errors

SimVisJones() : SolvableVisJones()

SimVisJones(VisSet& vs, Int seed=0, Double interval=DBL_MAX, Double deltat=1.0)

From VisSet - caching interval is in seconds.

Description

Prerequisite

Etymology

SimGJones describes random multiplicative gains to be used in the VisEquation. The Jones matrices are diagonal.

Synopsis

See VisEquation for definition of the Visibility Measurement Equation. See VisJones for how SimVisJones is to be used.

Motivation

The properties of a multiplicative component must be described for the VisEquation.

To Do

Member Description

SimGJones(VisSet& vs, Int seed, Distribution ampDist=normal, Double ampMean=1.0, Double ampWidth=0.1, Distribution phaseDist=normal, Double phaseMean=0.0, Double phaseWidth=0.1, Double interval=DBL_MAX, Double deltat=1.0)

Construct from VisSet. Supply seed for random number generator. the Width parameters represent rms for Normal and total range for Uniform distributions. Phase is in radians. Interval specifies the time variability of the gains, every interval has a new gain.
