20 | // Class for trigger analysis. | |
21 | // Digits are grouped in TRU's (384 cells? ordered fNTRUPhi x fNTRUEta). | |
22 | // The algorithm searches all possible 4x4 cell combinations per each TRU, | |
23 | // adding the digits amplitude and finding the maximum. Maximums are compared | |
24 | // to triggers threshold and they are set. Thresholds need to be fixed. | |
59264fa6 | 25 | // Last 2 modules are half size in Phi, I considered that the number of TRU |
26 | // is maintained for the last modules but decision not taken. If different, | |
27 | // then this must be changed. | |
