20 | // Class for trigger analysis. | |
0b2ec9f7 | 21 | // Digits are grouped in TRU's (384 cells ordered fNTRUPhi x fNTRUEta). |
22 | // The algorithm searches all possible 2x2 and nxn (n is a multiple of 4) cell | |
23 | // combinations per each TRU, adding the digits amplitude and finding the | |
24 | // maximum. Maxima are compared to triggers threshold and they are set. | |
25 | // Thresholds need to be fixed. Last 2 modules are half size in Phi, I considered | |
26 | // that the number of TRU is maintained for the last modules but decision not taken. | |
27 | // If different, then this must be changed. | |
