18 /// \class AliMUONReconstructor
20 /// Implementation of AliReconstructor for MUON subsystem.
22 /// The clustering mode and the associated parameters can be changed through the
23 /// AliMUONRecoParam object set in the reconstruction macro or read from the CDB
24 /// (see methods in AliMUONRecoParam.h file for details)
28 /// SIMPLEFIT : use the AliMUONClusterFinderSimpleFit clusterizer
30 /// SIMPLEFITV3 : SIMPLEFIT with preclustering=PRECLUSTERV3
32 /// MLEM : use AliMUONClusterFinderMLEM and AliMUONPreClusterFinder for preclustering (default)
33 /// MLEMV2 : MLEM with preclustering=PRECLUSTERV2
34 /// MLEMV3 : MLEM with preclustering=PRECLUSTERV3
36 /// PRECLUSTER : use only AliMUONPreClusterFinder. Only for debug as
37 /// the produced clusters do not have a position, hence the tracking will not
39 /// PRECLUSTERV2 : another version of the preclustering
40 /// PRECLUSTERV3 : yet another version of the preclustering
42 /// COG : use AliMUONClusterFinderCOG clusterizer. Not really a production
43 /// option either, as center-of-gravity is generally not a good estimate
44 /// of the cluster position...
46 /// PEAKCOG : COG cluster finder around local maxima
47 /// PEAKFIT : fit around local maxima with up to 3 peaks, COG otherwise
49 /// NOCLUSTERING : bypass completely the clustering stage
53 /// The behavior of the MUON reconstruction can also be changed, besides
54 /// the usual methods found in AliReconstruction (e.g. to disable tracking)
55 /// by using AliReconstruction::SetOption("MUON",options)
56 /// where options should be a space separated string.
58 /// Valid options are :
60 /// SAVEDIGITS : if you want to save in the TreeD the *calibrated* digits
61 /// that are used for the clustering
63 /// DIGITSTOREV1 : use the V1 implementation of the digitstore
64 /// DIGITSTOREV2R : use the V2R implementation of the digitstore
66 /// NOLOCALRECONSTRUCTION : for debug, to disable local reconstruction (and hence
67 /// "recover" old behavior)
69 /// TRIGGERDISABLE : disable the treatment of MUON trigger
71 /// NOFASTTRKDECODER : makes the digit maker class use the non-high performance decoder
72 /// AliMUONPayloadTracker instead of AliMUONTrackerDDLDecoder.
74 /// NOFASTTRGDECODER : makes the digit maker class use the non-high performance decoder
75 /// AliMUONPayloadTrigger instead of AliMUONTriggerDDLDecoder.
77 /// NOFASTDECODERS : makes the digit maker class use the non-high performance decoders
78 /// AliMUONPayloadTracker and AliMUONPayloadTrigger.
