Detailed Description

SimACohCalc: Model additive noise errors for the VisEquation.

Intended use:

Public interface

Prerequisite

• MeasurementComponents module
• VisSet class
• VisEquation class
• SimACoh class

Etymology

SimACohCalc describes random additive errors to be used in the VisEquation, calculated from parameters such as bandwidth, system temperature, integration time, dish diameter, and efficiencies.

Synopsis

See VisEquation for definition of the Visibility Measurement Equation. See ACoh for how SimACohCalc is to be used.

Motivation

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

Constructor & Destructor Documentation

casa::SimACohCalc::SimACohCalc	(	const casacore::Int	seed = 1,
		const casacore::Float	antefficiency = 0.80,
		const casacore::Float	correfficiency = 0.85,
		const casacore::Float	spillefficiency = 0.85,
		const casacore::Float	tau = 0.0,
		const casacore::Quantity &	trx = 50,
		const casacore::Quantity &	tatmos = 250,
		const casacore::Quantity &	tcmb = 2.7
	)

Construct from VisSet, seed and rms of additive noise (normal dist.) NOTE: rms is for the tau = 0.0 case, and is augmented as appropriate given tau, tatmos, trx (ie, all NON-atmospheric noise contributions), and airmass= 1/sin(ELEVATION).

If tau = 0.0, this defaults to the SimACoh case.
