9 | The macro MUONClusterInfo.C reads the ESDs or RecPoints and creates a tree of | |
10 | AliMUONClusterInfo objects which can be conveniently used to plot track to | |
11 | cluster residuals, cluster and pads properties. | |
12 | ||
13 | Usage: | |
14 | <pre> | |
15 | root [0] .L $ALICE_ROOT/MUON/MUONClusterInfo.C+ | |
16 | root [1] MUONClusterInfo(nevents, esdFileName, inFileName, outFileName); | |
17 | </pre> | |
18 | ||
19 | 1) <code> if ( esdFileName != "" ) </code>: | |
20 | ||
21 | Loop over ESD event and fill AliMUONClusterInfo object with cluster + | |
22 | corresponding track parameters. | |
23 | ||
24 | 2) <code> if ( inFileName != "" ) </code>: | |
25 | ||
26 | Loop over RecPoints and fill AliMUONClusterInfo object with cluster not | |
27 | attached to a track; | |
28 | ||
29 | 3) Write results in a new root file. | |

31 | \section calign_s2 How to run offline calibration and alignment tasks | |
32 | ||
33 | AliMUONAlignmentTask: | |
34 | ||
35 | It is an AliAnalysisTask to align the MUON spectrometer. The Task reads | |
36 | as input ESDs and feeds the MUONTracks to AliMUONAlignment. The alignment | |
6139aa84 | 37 | itself is performed by AliMillepede. An OCDB entry is written with the |
38 | alignment parameters. See AddTaskMuonAlignment.C for more details on usage | |
6c960a43 | 39 | |
40 | AliMUONChamberCalibrationTask: | |
41 | ||
42 | It is a AliAnalysisTaskSE to recalibrate the MUON spectrometers. The output is | |
43 | a TTree of AliMUONClusterInfo. | |
44 | ||
45 | ||
46 | The AliMUON*Task are designed to run in an analyis train of the Analysis | |
47 | Framework. The macros AddTaskMuon*.C can be used to add the task to an | |
48 | analysis train. An usage example based on the new standard AnalysisTrainNew.C | |
49 | will be provided soon. | |
