AliCosmicTracker

AliCosmicTracker(const Int_t dlev = 0, const TString tag = "test")

constructor

destructor

set esd event

Int_t Process(const TString tag = "", const Bool_t kprint = kFALSE)

double loop over combinations of esd tracks, cosmic event candidates sotred in fTrackStack

check whether the two tracks come from one cosmic ray

cut on track quality (kink, TPCrefit, findable ratio) and require TPC seed

return the error status in process

output to streamer

TClonesArray * FindCosmic(AliESDEvent* event, const Bool_t kadd)
