19 | // Class for trigger analysis. | |
0964c2e9 | 20 | // Digits are grouped in TRU's (Trigger Units). A TRU consists of 384 |
21 | // cells ordered fNTRUPhi x fNTRUEta. The algorithm searches all possible 2x2 | |
22 | // and nxn (n is a multiple of 2) cell combinations per each TRU, adding the | |
23 | // digits amplitude and finding the maximum. If found, look if it is isolated. | |
24 | // Maxima are transformed in ADC time samples. Each time bin is compared to the trigger | |
25 | // threshold until it is larger and then, triggers are set. Thresholds need to be fixed. | |
0b2ec9f7 | 26 | // Thresholds need to be fixed. Last 2 modules are half size in Phi, I considered |
27 | // that the number of TRU is maintained for the last modules but decision not taken. | |
28 | // If different, then this must be changed. | |
