18 // Class for trigger analysis.
19 // Digits are grouped in TRU's (Trigger Units). A TRU consist of 16x28
20 // crystals ordered fNTRUPhi x fNTRUZ. The algorithm searches all possible
21 // 2x2 and nxn (n multiple of 2) crystal combinations per each TRU, adding the
22 // digits amplitude and finding the maximum. If found, look if it is isolated.
23 // Maxima are transformed in ADC time samples. Each time bin is compared to the trigger
24 // threshold until it is larger and then, triggers are set. Thresholds need to be fixed.
27 // //Inside the event loop
