Function documentation
void GetInterpolation(const Float_t* x, const Short_t roc, Float_t* dx, TMatrixF** mR, TMatrixF** mPhi, TMatrixF** mZ)
Calculates the correction/distotring from a lookup table
type: 0 = correction
1 = distortion
void CreateLookupTable(AliTPCCorrection& tpcCorr, Float_t stepSize = 5.)
create lookup table for all phi,r,z bins
void CreateLookupTableSinglePhi(AliTPCCorrection& tpcCorr, Int_t iPhi, Float_t stepSize = 5.)
Lookup table for only one phi bin. Can be used for parallel processing
void CreateLookupTableFromResidualDistortion(THn& resDist)
create lookup table from residual distortions stored in a 3d histogram assume dimensions are r, phi, z
void CreateResidual(AliTPCCorrection* distortion, AliTPCCorrection* correction)
create lookup table from residual distortions calculated from distorted - correction
void ResetLimits()
void MergePhiTables(const char* files)
merge all lookup tables stored in 'files' with this one assume that each lookup table in each file has only one phi bin
void BuildExactInverse()
this method build the exact inverse of the standard distortion map for the the distortion man first needs to be calculated then the correction map will be overwritten
void FindClosestPosition(const Int_t binR, const Int_t binZ, const Int_t binPhi, const Float_t* xref, Float_t* xret)
AliTPCCorrectionLookupTable& operator=(const AliTPCCorrectionLookupTable& corr)
