Detailed Description

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

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

Member Function Documentation

void output ( std::ostream &  out)
