-// Geometry class for EMCAL : singleton
+// 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
+//
+// 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_FIRSTYEARV1 - geometry for December 2009 to December 2010 run period;
+// fixed bug for positions of modules inside SM
+// (first module has tilt 0.75 degree);
+// the sizes updated with last information from production
+// drawing (end of October 2010).
+//
+// EMCAL_COMPLETEV1: Same fixes as FIRSTYEAR and 10 SM instead of 10+2 half SM
+//
+// EMCAL_WSUC (Wayne State test stand)
+// = no definite equivalent in old notation, was only used by
+// Aleksei, but kept for testing purposes
+//
+// etc.
+
+//
+// Usage:
+// You can create the AliEMCALGeometry object independently from anything.
+// You have to use just the correct name of geometry. If name is empty string the
+// default name of geometry will be used.
+//
+// AliEMCALGeometry* g = AliEMCALGeometry::GetInstance(name,title); // first time
+// ..
+// g = AliEMCALGeometry::GetInstance(); // after first time
+//
+// MC: If you work with MC data you have to get geometry the next way:
+// == =============================
+// AliRunLoader *rl = AliRunLoader::Instance();
+// AliEMCALGeometry *geom = dynamic_cast<AliEMCAL*>(rl->GetAliRun()->GetDetector("EMCAL"))->GetGeometry();
