// Implementation version v1 of the PHOS particle identifier
// Particle identification based on the
-// - CPV information,
-// - Preshower information (in MIX or GPS2 geometries)
-// - shower width.
-
-// CPV or Preshower cluster should be clother in PHOS plane than fCpvEmcDistance (in cm).
-// This variable can be set by method SetCpvtoEmcDistanceCut(Float_t cut)
+// - RCPV: distance from CPV recpoint to EMCA recpoint.
+// - TOF
+// - PCA: Principal Components Analysis..
+// The identified particle has an identification number corresponding
+// to a 9 bits number:
+// -Bit 0 to 2: bit set if RCPV > fCpvEmcDistance (each bit corresponds
+// to a different efficiency-purity point of the photon identification)
+// -Bit 3 to 5: bit set if TOF < fTimeGate (each bit corresponds
+// to a different efficiency-purity point of the photon identification)
+// -Bit 6 to 9: bit set if Principal Components are
+// inside an ellipse defined by fX_center, fY_center, fA, fB, fAngle
+// (each bit corresponds to a different efficiency-purity point of the
+// photon identification)
//
-// One can set desirable ID method by the function SetIdentificationMethod(option).
-// Now the following options can be used together or separately :
-// - "disp": use dispersion cut on shower width
-// (width can be set by method SetDispersionCut(Float_t cut)
-// - "ell" : use cut on the axis of the ellipse, drown around shower
-// (this cut can be changed by SetShowerProfileCut(char* formula),
-// where formula - any function of two variables f(lambda[0],lambda[1]).
-// Shower is considered as EM if f() > 0 )
-// One can visualize current cuts calling method PlotDispersionCuts().
