Function documentation

AliCentralityGlauberFit(const char* filename)
 Standard constructor.
void SetRangeToFit(Double_t multmin, Double_t multmax)
 Set fit range.
void SetRangeToScale(Double_t scalemin)
 Set range where to scale simulated histo to data
void SetGlauberParam(Int_t Nmu, Double_t mulow, Double_t muhigh, Int_t Nk, Double_t klow, Double_t khigh, Int_t Nalpha, Double_t alphalow, Double_t alphahigh)
 Set Glauber parameters.
void MakeFits()
 Make fits.
void MakeFitsMinuitNBD(Double_t alpha = -1, Double_t mu = -1, Double_t k = -1)
 Make fits using Minuit.
TH1F * GlauberHisto(Double_t mu, Double_t k, Double_t alpha, TH1F* hDATA, Bool_t save = kFALSE)
 Get Glauber histogram.
Double_t CalculateChi2(TH1F* hDATA, TH1F* thistGlau)
 Note that for different values of neff the mc distribution is identical, just re-scaled below
 normalize the two histogram, scale MC up but leave data alone - that preserves error bars !!!!
TH1F * GetTriggerEfficiencyFunction(TH1F* hist1, TH1F* hist2)
 Get efficiency.
Double_t GetTriggerEfficiencyIntegral(TH1F* hist1, TH1F* hist2)
 Get eff integral.

 Save histograms.
Double_t NBD(Int_t n, Double_t mu, Double_t k) const
 Compute NBD.
TH1F * NBDhist(Double_t mu, Double_t k)
 Interface for TH1F.
void MinuitFcnNBD(Int_t& npar, Double_t* gin, Double_t& f, Double_t* par, Int_t iflag)
 FCN for minuit.
Double_t NBDFunc(const Double_t* p, const Double_t* x)
 TF1  interface.
TH1F * MakeAncestor(Double_t alpha)
