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 // Setting for systematic errors addition
34 [2] - systematic RMSSNP
35 [3] - systematic RMSTheta
36 [4] - systematic RMSCuravture - systematic error in 1/cm not in 1/pt
38 // How to add it example - 3 mm systematic error y, 3 cm systematic error z (drift)
39 Double_t sysError[5]={0.3,3, 0.3/150., 3./150.,0.3/(150*150.)}
