7The reconstruction is a multistage process, driven by the AliMUONReconstructor class :
8
9- We read the RAW data, convert them (convert them back for simulated data) to
10AliMUONDigit. Performed by AliMUONDigitMaker.
11- We calibrate the digits, by subtracting pedestals and multiplying by gains. Performed
12 by AliMUONDigitCalibrator. Calibrated digits might be saved (back) to TreeD.
13- We make clusters by associating digits, producing AliMUONRawCluster objects that end up
14 in TreeR of MUON.RecPoints#.root file(s). Steered by AliMUONClusterReconstructor. @ref AliMUONVClusterFinder "More..."
15
16Part of the reconstruction, but not really steered by AliMUONReconstructor, is the
17 last stage, the tracking, i.e. associating clusters to form tracks. Steered by AliMUONTracker.
18 Producing AliMUONTrack objects that end up in TreeT of MUON.Tracks#.root and AliESDMuonTrack objects
19that end up in the ESD (Event Summary Data), AliESDs.root file. @ref AliMUONVTrackReconstructor "More..."

fd3ef136 22\section rec_s1 How to tune the muon reconstruction
23
24Several options and adjustable parameters allow to tune the entire reconstruction.
25These can be changed by adding the following lines in the reconstruction macro (@ref runReconstruction.C) :
26
27<pre>
28 AliMUONRecoParam *muonRecoParam = AliMUONRecoParam::GetLow(High)FluxParam();
29 muonRecoParam->Use...();
30 muonRecoParam->Set...();
31 ...
32 AliRecoParam::Instance()->RegisterRecoParam(muonRecoParam);
33</pre>
34
35Have a look at @ref AliMUONRecoParam for the complete list
36of options/parameters with their purpose.

39\section rec_s2 How to convert MUON digit/cluster/track into ESD pad/cluster/track and vice versa
40
41The class @ref AliMUONESDInterface is doing the job.
42There are 2 ways of using this class:
431) using the static methods to convert the objects one by one (and possibly put them
44 into the provided store).
452) loading an entire ESDEvent and using the getters and/or the iterators
46 to access the corresponding MUON objects.
47Note: You can change (via static method) the type of the store this class is using.
