2.4.1.0 simulator.openfromms

NRAO Home > CASA > CASA Toolkit Reference Manual

simulator.openfromms - Function

2.4.1 Construct a simulator tool using an already existing MS

Description

A simulator tool can either operate on an existing MeasurementSet, predicting and/or corrupting data on the existing uvw coordinates - to do that open the MS with sm.openfromms(msname) or it can be used to create a new MeasurementSet from descriptions of the array configuration and the observational parameters. - to create a new MS, use sm.open(msname).

NOTE: sm.predict assumes the model image units are Jy/pixel, and in fact will overwrite the brightness units of the image itself!

Arguments


Inputs
ms	MeasurementSet to be processed
	allowed:	string
	Default:	’MS’

Returns
bool

Example

    sm.openfromms(’3C273XC1.MS’);
    sm.predict(’3C273XC1.imagename’);
    sm.setnoise(simplenoise=’10mJy’);
    sm.setgain(interval=’100s’, amplitude=0.01);
    sm.corrupt();
    sm.close();
