efad3788 19// Algorythm class to analyze PHOS events. In this class we demostrate,
20// how to handle reconstructed objects with AliPHSOIndexToObject.
21// As an example we propose sulotions for four most frequently used tasks:
22// DrawRecon(...) - to draw reconstructed objects in the PHOS plane,
23// very usefull in the debuging
24// InvarianMass(...) - to calculate "REAL" and "MIXED" photon pairs
25// invariant mass distributions
26// EnergyResoluition(...) -\ Energy and position resolutions of the
27// PositionResolution(...)-/ reconstructed photons
28// Contamination(...) - calculates contamination of the photon spectrum and
29// pobability of reconstruction of several primaries as
30// kGAMMA,kELECTRON etc.
31//
32// User Case:
e4761a49 33// root [0] AliPHOSAnalyze * a = new AliPHOSAnalyze("galice.root")
efad3788 34// // set the file you want to analyse
35// root [1] a->DrawRecon(1,3)
36// // plot RecObjects, made in event 1, PHOS module 3
37// root [2] a->DrawRecon(1,3,"PHOSRP","another PID")
38// // plot RecObjets made in the event 1, PHOS module 3,
39// // produced in the another reconstruction pass,
40// // which produced PHOS RecParticles ("PHOSRP") with
41// // title "another PID".
42// root [3] a->InvariantMass()
43// // Calculates "REAL" and "MIXED" invariant mass
44// // distributions of kGAMMA and (kGAMMA+kNEUTRALEM)
45// // and APPENDS this to the file "invmass.root"
46// root [4] a->PositionResolution()
47// // calculates two dimentional histos: energy of the primary
48// // photon vs distance betwin incedence point and reconstructed
49// // poisition. One can analyse the produced file position.root
50// // with macro PhotonPosition.C
51// root [5] a->EnergyResolution()
52// // calculates two dimentional histos: energy of the primary
53// // photon vs energy of the reconstructed particle. One can
54// // analyse the produced file energy.root
55// // with macro PhotonEnergy.C
56// root [6] a->Contamination()
57// // fills spectra of primary photons and several kinds of
58// // reconstructed particles, so that analyzing them one can
59// // estimate conatmination, efficiency of registration etc.
