19 // Class with TPC reconstruction parameters //
23 The reconstruction parameters are used in the AliTPCclustererMI and AliTPCtrackerMI
26 0. User speciefied it in reconstruction macro
27 1. if (not 0) from OCDB - AliTPCcalibDB::GetRecoParam(eventtype)
28 2. if (not 0 or 1) default parameter - High flux enevironment used
31 In the future reconstruction parameters should be changed on event basis
32 But for the moment, event types are still not defined
35 // Setting for systematic errors addition
38 [2] - systematic RMSSNP
39 [3] - systematic RMSTheta
40 [4] - systematic RMSCuravture - systematic error in 1/cm not in 1/pt
42 // How to add it example - 3 mm systematic error y, 3 cm systematic error z (drift)
43 Double_t sysError[5]={0.3,3, 0.3/150., 3./150.,0.3/(150*150.)}
44 param->SetSystematicError(sysError);
