qimager.selfcal - Function

Self-calibrate the MeasurementSet using a calibrater tool and model+component list

Synopsis selfcal(caltool, model, complist) To self-calibrate, first make a calibrater tool and set it up as required. Then use this tool function to do the selfcal. The steps coded in the tool function may also be done by hand, of course. These are:

1.: Call qimager.ft To Fourier transform the model and optional componentlist
2.: Call calibrater.solve to do the solution, optionally writing out tables containing gain information.
3.: Call calibrater.correct to do the correction of the data.

After the selfcal step, the next stage is to re-image the data using e.g. clean or nnls.

Description

Arguments

`caltool`	Glish name of calibrater tool
	`Allowed:`	`Any valid calibrater tool`
	`Default:`	`NONE!`
`model`	Name of images
	`Allowed:`	`Vector of strings`
`complist`	Name of component list
	`Allowed:`	`String`

Returns Bool

Example

imgr:=qimager('3C273XC1.ms')
cl:=calibrater('3C273XC1.ms')
cl.setsolve('T', 60, 'T', -1, '', F)
imgr.selfcal(cl, model='clean')
imgr.clean(model='newclean', image='newclean.restored')
