CF_TYPE casa::IlluminationConvFunc::getValue	(	Vector< CF_TYPE > &	,
		Vector< CF_TYPE > &
	)			[inline, virtual]

Given the pixel co-ordinates and an offset values, this returns the value of the convolution function.

This is however not used anywhere yet (and is therefore also not a pure virtual function).

Reimplemented from casa::ConvolutionFunction.

A support function which, for now, returns and integer ID corresponding to the on-sky frequency of the supplied VisBuffer.

Implements casa::ConvolutionFunction.

This method computes the average response function.

This is typically image-plane equivalent of the convolution functions, averaged over various axis. The precise averaging will be implementation dependent in the derived classes.
