2f77b146 23// Geometry of the 26th of november 2003 //
47d9b1cb 24// (circular instead of trapezoidal shapes as in previous versions //
2f77b146 25// plus changes in cell dimensions and offsets) : //
26// Scintillating cells are now 2 cm thick instead of 0.7 cm //
27// V0R sits between Z values -89.4 and -85.0 cm //
28// V0L sits between Z values +350.0 and +352.0 cm //
29// New coordinate system has been implemented in october 2003 //
