hi everybody,
i’m writing a macro that fits some spectra. I want the fit parameters saved in an output file.
I used a TGraph for the spectrum and a TF1 for the function that fits it.
I have everything ready but I don’t know which is the command that returns the values of the parameters.
I have something like this at the end of my macro:
“fit1->GetPar(0)” should return the first fit parameter, but it doesn’t work because it’s not the right command.
in other words, i want all the information given by “gStyle->SetOptFit(1)” saved in a file.
can you help me, please?
