19 /// \class AliMUONVTrackReconstructor
20 /// Virtual MUON track reconstructor in ALICE (class renamed from AliMUONEventReconstructor)
22 /// This class contains as data a pointer to the array of reconstructed tracks
24 /// It contains as methods, among others:
25 /// * EventReconstruct to build the muon tracks
26 /// * EventReconstructTrigger to build the trigger tracks
27 /// * ValidateTracksWithTrigger to match tracker/trigger tracks
29 /// Several options and adjustable parameters are available for both KALMAN and ORIGINAL
30 /// tracking algorithms. They can be changed by using:
31 /// AliMUONRecoParam *muonRecoParam = AliMUONRecoParam::GetLow(High)FluxParam();
32 /// muonRecoParam->Set...(); // see methods in AliMUONRecoParam.h for details
33 /// AliMUONReconstructor::SetRecoParam(muonRecoParam);
35 /// Main parameters and options are:
36 /// - *fgkSigmaToCutForTracking* : quality cut used to select new clusters to be
37 /// attached to the track candidate and to select good tracks.
38 /// - *fgkMakeTrackCandidatesFast* : if this flag is set to 'true', the track candidates
39 /// are made assuming linear propagation between stations 4 and 5.
40 /// - *fgkTrackAllTracks* : according to the value of this flag, in case that several
41 /// new clusters pass the quality cut, either we consider all the possibilities
42 /// (duplicating tracks) or we attach only the best cluster.
43 /// - *fgkRecoverTracks* : if this flag is set to 'true', we try to recover the tracks
44 /// lost during the tracking by removing the worst of the 2 clusters attached in the
46 /// - *fgkImproveTracks* : if this flag is set to 'true', we try to improve the quality
47 /// of the tracks at the end of the tracking by removing clusters that do not pass
48 /// new quality cut (the track is removed is it does not contain enough cluster anymore).
49 /// - *fgkComplementTracks* : if this flag is set to 'true', we try to improve the quality
50 /// of the tracks at the end of the tracking by adding potentially missing clusters
51 /// (we may have 2 clusters in the same chamber because of the overlapping of detection
52 /// elements, which is not handle by the tracking algorithm).
53 /// - *fgkSigmaToCutForImprovement* : quality cut used when we try to improve the
54 /// quality of the tracks.
