b2a60966 19// Implementation version v1 of the PHOS particle identifier
7acf6008 20// Particle identification based on the
21// - CPV information,
a4e98857 22// - Preshower information (in MIXT or GPS2 geometries)
7acf6008 23// - shower width.
a4e98857 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)
7acf6008 27//
28// One can set desirable ID method by the function SetIdentificationMethod(option).
a4e98857 29// Presently the following options can be used together or separately :
7acf6008 30// - "disp": use dispersion cut on shower width
31// (width can be set by method SetDispersionCut(Float_t cut)
a4e98857 32// - "ell" : use cut on the axis of the ellipse, drawn around shower
7acf6008 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//
a4e98857 38// use case:
39// root [0] AliPHOSPIDv1 * p1 = new AliPHOSPIDv1("galice.root")
40// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
41// root [1] p1->SetIdentificationMethod("disp ellipse")
42// root [2] p1->ExecuteTask()
43// root [3] AliPHOSPIDv1 * p2 = new AliPHOSPIDv1("galice1.root","ts1")
44// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
7acf6008 45// // reading headers from file galice1.root and TrackSegments
46// // with title "ts1"
a4e98857 47// root [4] p2->SetRecParticlesBranch("rp1")
7acf6008 48// // set file name for the branch RecParticles
a4e98857 49// root [5] p2->ExecuteTask("deb all time")
7acf6008 50// // available options
51// // "deb" - prints # of reconstructed particles
52// // "deb all" - prints # and list of RecParticles
53// // "time" - prints benchmarking results
