a3dfe79c 9// Geometry class for PHOS : singleton
10// PHOS consists of the electromagnetic calorimeter (EMCA)
11// and a charged particle veto either in the Subatech's version (PPSD)
12// or in the IHEP's one (CPV).
13// The EMCA/PPSD/CPV modules are parametrized so that any configuration
14// can be easily implemented
15// The title is used to identify the version of CPV used.
