qimagercomponenttest - Function

	Package	synthesis
	Module	qimager

Perform a test of component model processing using a standard MeasurementSet

Synopsis
qimagercomponenttest(size, doshift, doplot)

Description
Perform a test of component model processing. The dataset used is an observation of 3C273 at 8GHz using the C-configuration of the VLA. It is part of the AIPS++ distribution.

The test does the following:

• The uvfits file that is to be read in is in a standard place in the AIPS++ code source area.
• The MeasurementSet is read from the uvfits file.
• A component list is constructed and using in the subsequent processing. A point component is placed at the position of the core of 3C273, but specified in Galactic coordinates.
• The component model is used in predicting the model visibilities.
• A plot of the visibilities is made.
• The image is cleaned and restored. The center of the image is shifted to half way down the jet.

Returns
Bool
