Function documentation

AliMCinfo()
 Set 0-Pointers
AliMCinfo(const AliTRDtrackInfo::AliMCinfo& mc)
 Constructor
Int_t GetPID() const
 Translate pdg code to PID index
~AliMCinfo()
 Destructor
AliTRDtrackInfo::AliMCinfo& operator=(const AliTRDtrackInfo::AliMCinfo& mc)
 Assignment operator
Bool_t GetDirections(Float_t& x0, Float_t& y0, Float_t& z0, Float_t& dydx, Float_t& dzdx, Float_t& pt, Float_t& p, Float_t& eta, Float_t& phi, UChar_t& s) const
 Check for 2 track ref for the tracklet defined bythe radial position x0
 The "status" is a bit map and gives a more informative output in case of failure:
   - 0 : everything is OK
   - BIT(0) : 0 track refs found
   - BIT(1) : 1 track reference found
   - BIT(2) : dx <= 0 between track references
   - BIT(3) : dx > 0 && dx < 3.7 - tangent tracks
Bool_t PropagateKalman(TVectorD* x, TVectorD* y, TVectorD* z, TVectorD* dx, TVectorD* dy, TVectorD* dz, TVectorD* pt, TVectorD* dpt, TVectorD* budget, TVectorD* c, Double_t mass = -1) const
 Propagate Kalman from the first TRD track reference to
 last one and save residuals in the y, z and pt.

 This is to calibrate the dEdx and MS corrections
