Function documentation

AliPWG4HighPtQAMC()

AliPWG4HighPtQAMC(const char* name)

 Constructor. Initialization of Inputs and Outputs

void SetPtBinEdges(Int_t region, Double_t ptmax, Double_t ptBinWidth)

void ConnectInputData(Option_t* )

 Connect ESD and MC event handler here
 Called once

void CreateOutputObjects()

Create output objects

Bool_t SelectEvent()

 Decide if event should be selected for analysis

void Exec(Option_t* option)

 Main loop
 Called for each event

Bool_t PythiaInfoFromFile(const char* currFile, Float_t& fXsec, Float_t& fTrials)

 get the cross section and the trails either from pyxsec.root or from pysec_hists.root
 This is to called in Notify and should provide the path to the AOD/ESD file
 Copied from AliAnalysisTaskJetSpectrum2

Bool_t Notify()

 Implemented Notify() to read the cross sections
 and number of trials from pyxsec.root
 Copied from AliAnalysisTaskJetSpectrum2

AliGenPythiaEventHeader* GetPythiaEventHeader(AliMCEvent* mcEvent)

void Terminate(Option_t* )

 The Terminate() function is the last function to be called during
 a query. It always runs on the client, it can be used to present
 the results graphically or save the results to file.
