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);
24 // 1.c HLT clusters - Digits2Clusters and Digits2Clusters(AliRawReader* rawReader)
25 // invoke ReadHLTClusters()
27 // fUseHLTClusters - switches between different inputs
28 // 1 -> only TPC raw/sim data
29 // 2 -> if present TPC raw/sim data, otherwise HLT clusters
30 // 3 -> only HLT clusters
31 // 4 -> if present HLT clusters, otherwise TPC raw/sim data
34 // 2.a TTree with clusters - if SetOutput(TTree * tree) invoked
35 // 2.b TObjArray - Faster option for HLT
36 // 2.c TClonesArray - Faster option for HLT (smaller memory consumption), activate with fBClonesArray flag
38 // 3. Reconstruction setup
39 // see AliTPCRecoParam for list of parameters
40 // The reconstruction parameterization taken from the
41 // AliTPCReconstructor::GetRecoParam()
42 // Possible to setup it in reconstruction macro AliTPCReconstructor::SetRecoParam(...)
