19 // Implementation of the TPC clusterer
21 // 1. The Input data for reconstruction - Options
22 // 1.a Simulated data - TTree - invoked Digits2Clusters()
23 // 1.b Raw data - Digits2Clusters(AliRawReader* rawReader);
26 // 2.a TTree with clusters - if SetOutput(TTree * tree) invoked
27 // 2.b TObjArray - Faster option for HLT
28 // 2.c TClonesArray - Faster option for HLT (smaller memory consumption), activate with fBClonesArray flag
30 // 3. Reconstruction setup
31 // see AliTPCRecoParam for list of parameters
32 // The reconstruction parameterization taken from the
33 // AliTPCReconstructor::GetRecoParam()
34 // Possible to setup it in reconstruction macro AliTPCReconstructor::SetRecoParam(...)
