+// - Preshower information (in MIXT or GPS2 geometries)
// - shower width.

-// CPV or Preshower cluster should be clother in PHOS plane than fCpvEmcDistance (in cm).

+// CPV or Preshower clusters should be closer in PHOS plane than fCpvEmcDistance (in cm).
+// This parameter can be set by method SetCpvtoEmcDistanceCut(Float_t cut)

// One can set desirable ID method by the function SetIdentificationMethod(option).
-// Now the following options can be used together or separately :
+// Presently 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
+// - "ell" : use cut on the axis of the ellipse, drawn 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().
