Detailed Description

This class takes a visibility amplitude data object and a visibility amplitude model object, and then returns the log likelihood. by direct comparison to the observational data assuming that the measured visibility amplitudes has Gaussian errors.

This class also includes an utility function for computing the \( \chi^2 \) to assess fitquality
