Easier to keep track of the imstores that way CAREFUL: make sure you donot overwrite if you want to predict the model or subtract it to make residual

This should replace makeSDImage and makePSF etc in the long run But for now you can do the following images i.e string recognized by type "observed", "model", "corrected", "psf", "residual", "singledish-observed", "singledish", "coverage", "holography", "holography-observed" For holography the FTmachine should be SDGrid and the baselines.

selected should be those that are pointed up with the antenna which is rastering.

virtual casacore::Bool casa::SynthesisImager::selectData ( const SynthesisParamsSelect & selpars )

virtual

Copy constructor and assignment operator

Imager(const Imager&); Imager& operator=(const Imager&);

Reimplemented in casa::SynthesisImagerVi2.

virtual casacore::Bool casa::SynthesisImager::selectData	(	const casacore::String &	msname,

virtual void casa::SynthesisImager::setComponentList	(	const ComponentList &	cl,
		casacore::Bool	sdgrid = `false`
	)

virtual

Defining componentlist to use while degriding This should be called once...if multiple lists are used..they can be merged in one if sdgrid=true then image plane degridding is done.

void casa::SynthesisImager::setMovingSource ( const casacore::String & movsource )

This will set the movingSource_p.

virtual casacore::Bool casa::SynthesisImager::setWeightDensity ( const casacore::String & imagename = casacore::String("") )

virtual

set the weight density to the visibility iterator the default is to set it from the imagestore griwt() image Otherwise it will use this image passed here; useful for parallelization to share one grid to all children process

Reimplemented in casa::SynthesisImagerVi2.

casacore::Bool casa::SynthesisImager::toUseWeightImage	(	casacore::CountedPtr< FTMachine > &	ftm,
		casacore::String	mappertype

virtual casacore::Vector<SynthesisParamsSelect> casa::SynthesisImager::tuneSelectData ( )

virtual

casacore::Function to tune the data selection to intersect with image definition chosen This is to optimize the data selection so that unnecessary data is not parsed despite the user deciding to select so.

defineimage has to be run first (and thus selectData prior to that) otherwise an exception is thrown
