Function documentation

AliTPCPointCorrection()


 Kalman filter for global alignment


 Default constructor

AliTPCPointCorrection(const Text_t* name, const Text_t* title)




 Kalman filter for global alignment


 Non default constructor

~AliTPCPointCorrection()

AliTPCPointCorrection* Instance()

 Singleton implementation
 Returns an instance of this class, it is created if neccessary

Double_t GetDrOut(Bool_t isGlobal, Bool_t type, Double_t cx, Double_t cy, Double_t cz, Int_t sector)

  return radial correction

Double_t SGetDrOut(Bool_t isGlobal, Bool_t type, Double_t cx, Double_t cy, Double_t cz, Int_t sector)

 return radial correction - static function

Double_t GetDzOut(Bool_t isGlobal, Bool_t type, Double_t cx, Double_t cy, Double_t cz, Int_t sector)

Double_t SGetDzOut(Bool_t isGlobal, Bool_t type, Double_t cx, Double_t cy, Double_t cz, Int_t sector)

Double_t CorrectionOutR0(Bool_t isGlobal, Bool_t type, Double_t cx, Double_t cy, Double_t cz, Int_t sector)

 return dR correction - for correction version 0
 Parameters:
 isGlobal   - is the x in global frame
 type       - kTRUE - use sectors - kFALSE - only Side param
 cx, cy,cz  - cluster position
 sector     - sector number

Double_t RPhiCOGCorrection(Int_t sector, Int_t padrow, Float_t pad, Float_t cy, Float_t y, Float_t z, Float_t ky, Float_t qMax, Float_t threhsold)

 Calculates COG corection in RPHI direction
 cluster and track position  y is supposed to be corrected before for other effects
 (e.g ExB and alignemnt)
 Rphi distortion dependeds on the distance to the edge-pad, distance to the wire edge and
 relative distance to the center of the pad. Therefore the y position is trnsfromed to the
 pad coordiante frame (correction offset (ExB alignemnt) substracted).

 Input parameters:

 sector - sector number - 0-71  - cl.GetDetector()
 padrow - padrow number -0-63 -IROC 0-95 OROC - cl->GetRow()
 pad    - mean pad number  - cl->GetPad()
 cy     - cluster y        - cl->GetY()
  y     - track -or cluster y
  qMax  - cluster max charge - cl-.GetMax()
  threshold - clusterer threshold

Double_t CorrectionOutZ0(Bool_t isGlobal, Bool_t type, Double_t cx, Double_t cy, Double_t cz, Int_t sector)

 return dR correction - for correction version 0
 Parameters:
 isGlobal   - is the x in global frame
 type       - kTRUE - use sectors - kFALSE - only Side param
 cx, cy,cz  - cluster position
 sector     - sector number

Double_t GetEdgeQ0(Int_t sector, Int_t padrow, Float_t y)
