Function documentation

AliFlowAnalysisWithScalarProduct()

ctor

~AliFlowAnalysisWithScalarProduct()

destructor

void Init()

Define all histograms
printf("---Analysis with the Scalar Product Method--- Init\n");
printf("--- fNormalizationType %d ---\n", fNormalizationType);
save old value and prevent histograms from being added to directory
to avoid name clashes in case multiple analaysis objects are used
in an analysis

void Make(AliFlowEventSimple* anEvent)

 Scalar Product method

void GetOutputHistograms(TList* outputListHistos)

get pointers to all output histograms (called before Finish())

void Finish()

calculate flow and fill the AliFlowCommonHistResults

void WriteHistograms(TDirectoryFile* outputFileName) const

store the final results in output .root file

Double_t CalculateStatisticalError(Int_t RFPorPOI, Int_t PTorETA, Int_t bin, Double_t errV) const

calculate the statistical error for differential flow for bin b

Double_t ComputeResolution(Double_t x) const

 Computes resolution for Event Plane method
