18 /// \class AliMUONReconstructor
20 /// Implementation of AliReconstructor for MUON subsystem.
22 /// The clustering mode and the associated parameters can be changed by using
23 /// AliMUONRecoParam *muonRecoParam = AliMUONRecoParam::GetLow(High)FluxParam();
24 /// muonRecoParam->Set...(); // see methods in AliMUONRecoParam.h for details
25 /// AliRecoParam::Instance()->RegisterRecoParam(muonRecoParam);
29 /// SIMPLEFIT : use the AliMUONClusterFinderSimpleFit clusterizer
31 /// SIMPLEFITV3 : SIMPLEFIT with preclustering=PRECLUSTERV3
33 /// MLEM : use AliMUONClusterFinderMLEM and AliMUONPreClusterFinder for preclustering (default)
34 /// MLEMV2 : MLEM with preclustering=PRECLUSTERV2
35 /// MLEMV3 : MLEM with preclustering=PRECLUSTERV3
37 /// PRECLUSTER : use only AliMUONPreClusterFinder. Only for debug as
38 /// the produced clusters do not have a position, hence the tracking will not
40 /// PRECLUSTERV2 : another version of the preclustering
41 /// PRECLUSTERV3 : yet another version of the preclustering
43 /// COG : use AliMUONClusterFinderCOG clusterizer. Not really a production
44 /// option either, as center-of-gravity is generally not a good estimate
45 /// of the cluster position...
47 /// PEAKCOG : COG cluster finder around local maxima
48 /// PEAKFIT : fit around local maxima with up to 3 peaks, COG otherwise
50 /// NOCLUSTERING : bypass completely the clustering stage
54 /// The behavior of the MUON reconstruction can also be changed, besides
55 /// the usual methods found in AliReconstruction (e.g. to disable tracking)
56 /// by using AliReconstruction::SetOption("MUON",options)
57 /// where options should be a space separated string.
59 /// Valid options are :
61 /// SAVEDIGITS : if you want to save in the TreeD the *calibrated* digits
62 /// that are used for the clustering
64 /// DIGITSTOREV1 : use the V1 implementation of the digitstore
65 /// DIGITSTOREV2R : use the V2R implementation of the digitstore
67 /// NOLOCALRECONSTRUCTION : for debug, to disable local reconstruction (and hence
68 /// "recover" old behavior)
70 /// TRIGGERDISABLE : disable the treatment of MUON trigger
72 /// USEFASTDECODER : makes the digit maker class use the high performance decoder
73 /// AliMUONTrackerDDLDecoder instead of AliMUONPayloadTracker.
