10 // Class for trigger analysis.
11 // Digits are grouped in TRU's (Trigger Units). A TRU consist of 16x28
12 // crystals ordered fNTRUPhi x fNTRUZ. The algorithm searches all possible
13 // 2x2 and nxn (n multiple of 4) crystal combinations per each TRU, adding the
14 // digits amplitude and finding the maximum. Maxima are transformed in ADC
15 // time samples. Each time bin is compared to the trigger threshold until it is larger
16 // and then, triggers are set. Thresholds need to be fixed.
19 // //Inside the event loop
20 // AliPHOSTrigger *tr = new AliPHOSTrigger();//Init Trigger
21 // tr->SetL0Threshold(100);
22 // tr->SetL1JetLowPtThreshold(1000);
23 // tr->SetL1JetHighPtThreshold(20000);
24 // tr->Trigger(); //Execute Trigger
25 // tr->Print(""); //Print results
