AliUEHistograms

Function documentation

AliUEHistograms(const char* name = "AliUEHistograms", const char* histograms = "", const char* binning = 0)

 Constructor

 the string histograms defines which histograms are created:
    1 = NumberDensitypT
    2 = SumpT
    3 = NumberDensityPhi
    4 = NumberDensityPhiCentrality (other multiplicity for Pb)

AliUEHistograms(const AliUEHistograms& c)

 AliUEHistograms copy constructor

~AliUEHistograms()

 Destructor

void DeleteContainers()

AliUEHist* GetUEHist(Int_t id)

 returns AliUEHist object, useful for loops

Int_t CountParticles(TList* list, Float_t ptMin)

 counts the number of particles in the list with a pT above ptMin
 TODO eta cut needed here?

void Fill(Int_t eventType, Float_t zVtx, AliUEHist::CFStep step, AliVParticle* leading, TList* toward, TList* away, TList* min, TList* max)

 fills the UE event histograms

 this function needs the leading (track or jet or ...) and four lists of AliVParticles which contain the particles/tracks to be filled in the four regions

void FillRegion(AliUEHist::Region region, Float_t zVtx, AliUEHist::CFStep step, AliVParticle* leading, TList* list, Int_t multiplicity)

 loops over AliVParticles in list and fills the given region at the given step

 fills the fNumberDensityPhi histogram

 this function need a list of AliVParticles which contain the particles/tracks to be filled

 if mixed is non-0, mixed events are filled, the trigger particle is from particles, the associated from mixed
 if weight < 0, then the pt of the associated particle is filled as weight
