I have a short question and unfortunately I didn’t find the answer: I want to fit a THF2 with a TF2 function (2D Gaussian in my case; works fine). For TF1 I can use TFitResults to get chi square and thus evaluate the goodness. Is there anything like that for TF2?
This is the result of the fit in the terminal. I don’t know what the values for FCN and EDM mean and if they have any information.
FCN=19.7874 FROM MIGRAD STATUS=CONVERGED 240 CALLS 241 TOTAL
