image.deconvolvefrombeam - Function
1.1.1 Helper function to deconvolve the given source Gaussian from a beam Gaussian
to return a model Gaussian
Description
This is a helper function. It is to provide a way to deconvolve gaussians from
other gaussians if that is what is needed for example removing a beam
Gaussian from a Gaussian source. To run this function the tool need not be
attached to an image.
The return value is a record that contains the fit param and the return value is a boolean which is set to true if fit model is a point source
Arguments
