Hi every one,
                 Actually I want to know that is it necessary to fit Ei, 3rd, 4th, cumulant
in the fitting procedure .If yes then please tell me  how to get them
involve in the fit .when I give parameter like   guess 3rd, guess 4th .
Artemis dont take them . One more thing is that I am fitting
Cu foil, CuO and Cu2O , so how many number of paths should I take .
