-// Geometry of the 19th of april 2002 //
+// Geometry of the 26th of november 2003 //
// (circular instead of trapezoidal shapes as in previous versions //
+// plus changes in cell dimensions and offsets) : //
+// Scintillating cells are now 2 cm thick instead of 0.7 cm //
+// V0R sits between Z values -89.4 and -85.0 cm //
+// V0L sits between Z values +350.0 and +352.0 cm //
+// New coordinate system has been implemented in october 2003 //
