Fit the following data:
const int nBins = 60;
Double_t data[nBins] =
{6,1,10,12,6,13,23,22,15,21,23,26,36,25,27,35,40,44,66,81,75,57,48,45,46,41,35,36,53,32,40,37,38,31,36,44,42,37,32,32,43,44,35,33,33,39,29,41,32,44,26,39,29,35,32,21,21,15,25,15 };
to the following function:
a) gaussian
b) Lorenzian peak
// Lorenzian peak function
Double_t lorentzianPeak(Double_t *x, Double_t *par){
return (0.5*par[0]*par[1]/Tmath::Pi())/
TMath::Max(1.e-10,(x[0]-par[2])*(x[0]-par[2])
+ .25*par[1]*par[1]);
}
c) a gaussian + a cuadratic background
d) a Lorenzian peak + a quadratic background
