Detailed Description

TPC cluster error, shape and charge parameterization as function of drift length and inclination angle.

TPC cluster error and shape parameterization.

Following notation is used in following Int_t dim 0 - y direction 1 - z direction

Int_t type 0 - short pads 1 - medium pads 2 - long pads Float_t z - drift length

Float_t angle - tangent of inclination angle at given dimension

Implemented parameterization

  1. Resolution as function of drift length and inclination angle 1.a) GetError0(Int_t dim, Int_t type, Float_t z, Float_t angle) Simple error parameterization as derived from analytical formula only linear term in drift length and angle^2 The formula is valid only with precission +-5% Separate parameterization for differnt pad geometry 1.b) GetError0Par Parabolic term correction - better precision

    1.c) GetError1 - JUST FOR Study Similar to GetError1 The angular and diffusion effect is scaling with pad length common parameterization for different pad length

  2. Error parameterization using charge 2.a) GetErrorQ GetError0+ adding 1/Q component to diffusion and angluar part 2.b) GetErrorQPar GetError0Par+ adding 1/Q component to diffusion and angluar part 2.c) GetErrorQParScaled - Just for study One parameterization for all pad shapes Smaller precission as previous one

Example how to retrieve the paramterization:

AliCDBManager::Instance()->SetDefaultStorage("local://$ALICE_ROOT/OCDB");
AliCDBManager::Instance()->SetRun(0)
AliTPCClusterParam * param = AliTPCcalibDB::Instance()->GetClusterParam();
AliTPCClusterParam::SetInstance(param);
TF1 f1("f1","AliTPCClusterParam::SGetError0Par(1,0,x,0)",0,250);

Example how to create parameterization: Note resol is the resolution tree created by AliTPCcalibTracks

AliTPCClusterParam *param = new AliTPCClusterParam;
param->FitData(Resol);
AliTPCClusterParam::SetInstance(param);
