// 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 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
+//
// 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.
