19 | // Implementation version v0 of the PHOS particle identifier | |
20 | // Particle identification based on the | |
21 | // - CPV information, | |
22 | // - Preshower information (in MIXT or GPS2 geometries) | |
23 | // - shower width. | |
24 | // | |
25 | // CPV or Preshower clusters should be closer in PHOS plane than fCpvEmcDistance (in cm). | |
26 | // This parameter can be set by method SetCpvtoEmcDistanceCut(Float_t cut) | |
27 | // | |
28 | // One can set desirable ID method by the function SetIdentificationMethod(option). | |
29 | // Presently the following options can be used together or separately : | |
30 | // - "disp": use dispersion cut on shower width | |
31 | // (width can be set by method SetDispersionCut(Float_t cut) | |
32 | // - "ell" : use cut on the axis of the ellipse, drawn around shower | |
33 | // (this cut can be changed by SetShowerProfileCut(char* formula), | |
34 | // where formula - any function of two variables f(lambda[0],lambda[1]). | |
35 | // Shower is considered as EM if f() > 0 ) | |
36 | // One can visualize current cuts calling method PlotDispersionCuts(). | |
37 | // | |
38 | // use case: | |
39 | // root [0] AliPHOSPIDv0 * p1 = new AliPHOSPIDv0("galice.root") | |
40 | // Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated | |
41 | // root [1] p1->SetIdentificationMethod("disp ellipse") | |

44 | // Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated | |
45 | // // reading headers from file galice1.root and TrackSegments | |

47 | // root [4] p2->SetRecParticlesBranch("rp1") | |
48 | // // set file name for the branch RecParticles | |
49 | // root [5] p2->ExecuteTask("deb all time") | |
