Dear Experts,
Unfortunateley I have two problems that I can’t solve.
- RooHistPdf Normalization:
If I apply binning to my RooDataHist to reduce statistical fluctuations in my RooHistPdf the produced PDF doesn’t take the binning in account when it normalizes, so I can’t use it. I am sure, this problem can be solved with one simple command, which I just can’t find… example code:
RooRealVar Jpsict(“Jpsict”,“c #tau [mm]”,-1,2.5);
RooDataSet* data = (RooDataSet*)fIn->Get(“data”);
RooBinning rb(-1,2.5);
rb.addUniform(2,-1,0);
rb.addUniform(20,0,1);
rb.addUniform(2,1,2.5);
Jpsict.setBinning(rb);
RooDataHist realdatahist(“realdatahist”,“realdatahist”,RooArgSet(Jpsict),*data);
RooHistPdf histNonPrompt(“histNonPrompt”,“histNonPrompt”,Jpsict,realdatahist);
- Convolution in CMSSW framework:
I have to use convolution for my fit (other than RooDecay), but as I have to use the RooFit version (5.25.02-cms6) from the Root implemented in the CMSSW framework (ROOT 5.22/00d), I don’t know how I can do it, as there is no FFTW package compiled. Is there any possibility to implement this FFTW package from “outside”?
Thank you for your time,
Valentin Knünz
