class AliTRDpidESD: public TObject
Implementation of the TRD PID class Assigns the electron and pion likelihoods to each ESD track. The function MakePID(AliESDEvent *event) calculates the probability of having dedx and a maximum timbin at a given momentum (mom) and particle type k from the precalculated distributions.

Function documentation
Int_t MakePID(AliESDEvent *const event)
This function calculates the PID probabilities based on TRD signals The method produces probabilities based on the charge and the position of the maximum time bin in each layer. The dE/dx information can be used as global charge or 2 to 3 slices. Check AliTRDCalPID and AliTRDCalPIDRefMaker for the actual implementation. Author Alex Bercuci (A.Bercuci@gsi.de) 2nd May 2007
Bool_t RecalculateTrackSegmentKine(AliESDtrack *const t, Int_t plan, Float_t& mom, Float_t& length)
Retrive momentum "mom" and track "length" in TRD chamber from plane "plan" according to information stored in AliESDtrack "t". Origin Alex Bercuci (A.Bercuci@gsi.de)
