Multi-source fitting in the uv-domain #12

This would be the ideal form for fitting as it removed the issue of deconvolution, and multiple sources can be fit for simultaneously. This was purposed in Chang and Refregier 2001 using the gridded visibilities for computational efficiency.

A starting point is to transform a small FoV image to uv-domain and try to fit for shapelets. Could use an image-domain source finder to guess the initial size and position parameters.
