19 // Class for trigger analysis.
20 // Digits are grouped in TRU's (Trigger Units). A TRU consist of 16x28
21 // crystals ordered fNTRUPhi x fNTRUZ. The algorithm searches all possible
22 // 2x2 and nxn (n multiple of 4) crystal combinations per each TRU, adding the
23 // digits amplitude and finding the maximum. Iti is found is maximum 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.
28 // //Inside the event loop
29 // AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
30 // tr->SetL0Threshold(100);
31 // tr->SetL1JetLowPtThreshold(1000);
32 // tr->SetL1JetHighPtThreshold(20000);
34 // tr->Trigger(); //Execute Trigger
35 // tr->Print(""); //Print data members after calculation.
