14 | // Implementation of the PHOS manager class for fast simulations | |
15 | // Tracks particles until the reach a grossly designed PHOS module | |
16 | // Modify the particles property (momentum, energy, type) according to | |
17 | // the PHOS response function. The result is called a virtual reconstructed | |
18 | // particle. | |
