Function documentation

TObjArray * GetObjArray()

return fgObjArray, initialized if null

TObjArray * GetObj(const Bool_t kinvq, const Double_t mag, const Int_t charge)

return calib obj

void DeleteObjArray()

delete calib obj

Bool_t GenerateOCDB(const Int_t run = -1, const TString path = "local://./")

generate OCDB object PHQ, do like
AliTRDdEdxCalibUtils::GenerateOCDB(run, "local://./")
if fgObjArray==0x0, generate default one
else generate according to fgObjArray

void DeleteHistArray()

delete calib hist

THnBase * GetHistAt(const Int_t iter)

void IniHistArray(TList* list, const Bool_t kNoInv)

initialize calib hist, list should not own the hist, or list->Clear/delete hist should not be called

Bool_t ReadHistArray(const TString filename, const TString listname)

used in AliTRDPreprocessorOffline
read in calib hist from file, only for PHQ

void FillHist(const Int_t ncls, const TVectorD* arrayQ, const TVectorD* arrayX, THnBase* hcalib, const Double_t scale)

fill calibration hist

void FillHist(const AliTRDtrackV1* trdv1, const Bool_t kinvq, const Double_t mag, const Int_t charge, const Double_t scale)

get cluster Q and fill calib hist, if kinvq = kTRUE, 1/Q is filled

Double_t GetCalibTPCscale(const Int_t tpcncls, const Double_t tpcsig)

the scale used in calibration

void GetPHCountMeanRMS(const TH1D* hnor, TH1D*& hmean)

calculate from the ph calib hist the (mean-3sigma) ph-count in the chamber, save in the TH1D output

TObjArray* HistToObj(const THnBase* hh, Int_t run = -999, TList* lout = 0x0, TTreeSRedirector* calibStream = 0x0)

produce calibration objects

void SetObjArray(TObjArray* obj)

{fgObjArray = obj;}

AliTRDdEdxCalibHistArray * GetHistArray()

{return fgHistArray;}
