Function documentation

AliITSdEdxAnalyzer()

 default constructor

AliITSdEdxAnalyzer(const Int_t npbins, const Float_t pmin, const Float_t pmax)

 standard constructor

~AliITSdEdxAnalyzer()

 destructor

void SetMomentumBins(const Int_t npbins, const Float_t pmin, const Float_t pmax)

 Kill exisiting histos, set new binning, book new histos

void DeleteHistos()

 deletes the hitograms

void BookHistos()

 defines the output histograms

void ReadEvent(const AliESDEvent* ev, AliStack* stack = 0)

 Fill histos
 if stack is !=0 MC truth is used to define particle specie
 else TPC pid is used to define particle specie

Int_t GetPaticleIdFromTPC(const AliESDtrack* track) const

 Returns the particle specie as identified by TPC

Double_t BetheBloch(const Float_t p, const Float_t m) const

 Computes expected dE/dx value for given particle specie and momentum

TGraph* GetBetheBlochGraph(const Int_t pdgcode) const

 Fills a TGraph with Bethe-Bloch expe
