FlowModelCalculator

Installation:

git clone https://devel.mephi.ru/PEParfenov/FlowModelCalculator.git

cd FlowModelCalculator/ mkdir build cd build/ cmake ..

Centrality determination. Usage:

1. Get multiplicity histogram:

   root -l
   .L Centrality/libCentrality.so
   TChain *chain = new TChain("mctree")
   chain->Add("...") // Add files into TChain
   MultReader *multReader = new MultReader(chain)
   multReader->Loop("OUTPUTNAME") // Output of the root file
   

2. Calculate centrality:

   root -l
   .L Centrality/libCentrality.so
   TFile *fi = new TFile("...","read") // Output file from previous step
   TH1F *hist = (TH1F*) fi->Get("hMult")
   CentralityCalculator *centCalc = new CentralityCalculator()
   centCalc->SetModel("MODEL_NAME")
   centCalc->SetEnergy(ENERGY)
   centCalc->SetHistogram(hist)
   centCalc->Calc();
   
   Int_t centrality = centCalc->GetCentrality(mult)
