-// Algorythm class to analyze PHOSv1 events:
-// Construct histograms and displays them.
-// Use the macro EditorBar.C for best access to the functionnalities
+// Algorythm class to analyze PHOS events. In this class we demostrate,
+// how to handle reconstructed objects with AliPHSOIndexToObject.
+// As an example we propose sulotions for four most frequently used tasks:
+// DrawRecon(...) - to draw reconstructed objects in the PHOS plane,
+// very usefull in the debuging
+// InvarianMass(...) - to calculate "REAL" and "MIXED" photon pairs
+// invariant mass distributions
+// EnergyResoluition(...) -\ Energy and position resolutions of the
+// PositionResolution(...)-/ reconstructed photons
+// Contamination(...) - calculates contamination of the photon spectrum and
+// pobability of reconstruction of several primaries as
+// kGAMMA,kELECTRON etc.
+//
+// User Case:
+// root [0] AliPHOSAnalyzer * a = new AliPHOSAnalyzer("galice.root")
+// // set the file you want to analyse
+// root [1] a->DrawRecon(1,3)
+// // plot RecObjects, made in event 1, PHOS module 3
+// root [2] a->DrawRecon(1,3,"PHOSRP","another PID")
+// // plot RecObjets made in the event 1, PHOS module 3,
+// // produced in the another reconstruction pass,
+// // which produced PHOS RecParticles ("PHOSRP") with
+// // title "another PID".
+// root [3] a->InvariantMass()
+// // Calculates "REAL" and "MIXED" invariant mass
+// // distributions of kGAMMA and (kGAMMA+kNEUTRALEM)
+// // and APPENDS this to the file "invmass.root"
+// root [4] a->PositionResolution()
+// // calculates two dimentional histos: energy of the primary
+// // photon vs distance betwin incedence point and reconstructed
+// // poisition. One can analyse the produced file position.root
+// // with macro PhotonPosition.C
+// root [5] a->EnergyResolution()
+// // calculates two dimentional histos: energy of the primary
+// // photon vs energy of the reconstructed particle. One can
+// // analyse the produced file energy.root
+// // with macro PhotonEnergy.C
+// root [6] a->Contamination()
+// // fills spectra of primary photons and several kinds of
+// // reconstructed particles, so that analyzing them one can
+// // estimate conatmination, efficiency of registration etc.
