Hi
one question: I have a code like that
Loop
- Fit my data
- Get my mean with error with:
RooRealVar* mean_fitresult = (RooRealVar)fr->floatParsFinal()->find(“mean_jpsi”);
end of loop
How fill a histo with the mean-fitresult value ?
I don’t know how to fill the histo at each loop with Roofit
Hi,
If you want to fill a TH1, you can retrieve the
value of a RooRealVar through getVal(), e.g.
myTH->fill(mean_fitresult->getVal()) ;
If you want to fill a RooDataHist you do this
as follows
// before the loop
RooDataHist dh(“dh”,“dh”,*mean_fitresult) ;
// in the loop
dh.add(*mean_fitresult) ;
