19 // Class for trigger analysis.
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.
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.
31 // //Inside the event loop
32 // AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
33 // tr->SetL0Threshold(100); //Arbitrary threshold values
34 // tr->SetL1JetLowPtThreshold(1000);
35 // tr->SetL1JetMediumPtThreshold(10000);
36 // tr->SetL1JetHighPtThreshold(20000);
