23 | The reconstruction parameters are used in the AliTPCclustererMI and AliTPCtrackerMI | |
24 | ||
25 | They are retrieved: | |
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 | |
29 | ||
30 | FIXME: | |
31 | In the future reconstruction parameters should be changed on event basis | |
32 | But for the moment, event types are still not defined | |
