// Geometry class for EMCAL : singleton
-
// EMCAL consists of layers of scintillator and lead
-
+// with scintillator fiber arranged as "shish-kebab" skewers
// Places the the Barrel Geometry of The EMCAL at Midrapidity
-
-// between 0 and 120 degrees of Phi and
-
+// between 80 and 180(or 190) degrees of Phi and
// -0.7 to 0.7 in eta
-
-// Number of Modules and Layers may be controlled by
-
-// the name of the instance defined
-
-// EMCALArch2x has more modules along both phi and eta
-
-// EMCALArchxa has less Layers in the Radial Direction
-
+//
+// EMCAL geometry tree:
+// EMCAL -> superModule -> module -> tower(cell)
+// Indexes
+// absId -> nSupMod -> nModule -> (nIphi,nIeta)
+//
+// Name choices:
+// EMCAL_PDC06 (geometry used for PDC06 simulations, kept for backward compatibility)
+// = equivalent to SHISH_77_TRD1_2X2_FINAL_110DEG in old notation
+// EMCAL_COMPLETE (geometry for expected complete detector)
+// = equivalent to SHISH_77_TRD1_2X2_FINAL_110DEG scTh=0.176 pbTh=0.144
+// in old notation
+// EMCAL_WSUC (Wayne State test stand)
+// = no definite equivalent in old notation, was only used by
+// Aleksei, but kept for testing purposes
+//
+// etc.
