52 | // AliMUONRecoDisplay // | |
53 | // // | |
54 | // This class subclasses AliDisplay and provides display of // | |
55 | // reconstructed tracks with following functionality : // | |
56 | // - front/top/side/3D display of MUON reconstructed tracks // | |
57 | // as polylines ; // | |
58 | // - context menu activated when the main pad is right-clicked // | |
59 | // The context menu contains following functions : // | |
60 | // * SetDrawHits() - switches on or off Geant hits ; // | |
61 | // * CutMomentum() - displays only tracks within Pmin - Pmax // | |
62 | // * ListTracks() - prints ID and momentum info. for all // | |
63 | // tracks within momentum range Pmin,Pmax ; // | |
64 | // * Highlight() - shows only one selected reco. track // | |
65 | // and its best matching Geant track; // | |
66 | // * UnHighlight() - self explaining; // | |
67 | // * RecoEfficiency() - compute reco. efficiency for all events// | |
68 | // from galice.root file; also fake track percentage; make // | |
69 | // plots for momentum precision // | |
70 | // * XYPlot() - make X-Y plots of reconstructed and // | |
71 | // generated tracks in all chambers // | |
72 | // // | |
73 | // Starting : generate and reconstruct events, then use the // | |
74 | // MUONrecodisplay.C macro // | |
75 | // // | |
