59264fa6 | 12 | // Digits are grouped in TRU's (Trigger Units). A TRU consist of 384 cells |
0964c2e9 | 13 | // ordered fNTRUPhi x fNTRUEta matrix. The algorithm searches all possible |
14 | // 2x2 and nxn (n multiple of 4) crystal combinations per each TRU, adding the | |
15 | // digits amplitude and finding the maximum. It is found is maximum is isolated. | |
16 | // Maxima are transformed in adc time samples. Each time bin is compared to the | |
17 | // trigger threshold until it is larger and then, triggers are set. | |
18 | // Thresholds need to be fixed. | |
59264fa6 | 19 | // Last 2 modules are half size in Phi, I considered that the number |
20 | // of TRU is maintained for the last modules but final decision has not | |
21 | // been taken. If different, then this must to be changed. | |
