27//*-*
28//*-* The following structure members are set to 1 if the option is selected:
29 int Quiet; // "Q" Quiet mode. No print
30 int Verbose; // "V" Verbose mode. Print results after each iteration
31 int Bound; // "B" When using pre-defined functions user parameter settings are used instead of default one
32 int Chi2; // "X" For fitting THnsparse use chi2 method (default is likelihood)
33 int PChi2; // "P" Use Pearson chi2 built with the expected error instead of the observed ones
34 int Like; // "L" Use Log Likelihood. Default is chisquare method except fitting THnsparse
35 int User; // "U" Use a User specified fitting algorithm (via SetFCN)
36 int W1; // "W" Set all the weights to 1. Ignore error bars
37 int Errors; // "E" Performs a better error evaluation, calling HESSE and MINOS
38 int More; // "M" Improve fit results.
39 int Range; // "R" Use the range stored in function
40 int Gradient; // "G" Option to compute derivatives analytically
41 int Nostore; // "N" If set, do not store the function graph
42 int Nograph; // "0" If set, do not display the function graph
43 int Plus; // "+" Add new function (default is replace)
44 int Integral; // "I" Use function integral instead of function in center of bin
45 int Nochisq; // "C" In case of linear fitting, don't calculate the chisquare
46 int Minuit; // "F" If fitting a polN, switch to minuit fitter
47 int NoErrX; // "EX0" or "T" When fitting a TGraphErrors do not consider error in coordinates
48 int Robust; // "ROB" or "H": For a TGraph use robust fitting
49 int StoreResult; // "S": Stores the result in a TFitResult structure
50 int BinVolume; // "WIDTH": scale content by the bin width/volume
51 double hRobust; // value of h parameter used in robust fitting
52 ROOT::Fit::ExecutionPolicy ExecPolicy; // Choose the execution Policy: "SERIAL", "MULTITHREAD" or "MULTIPROCESS"
