9 | // Class for trigger analysis. | |
10 | // Digits are grouped in TRU's (Trigger Units). A TRU consist of 384 cells | |
11 | // ordered fNTRUPhi x fNTRUZ. The algorithm searches all possible | |
12 | // 4x4 crystal combinations per each TRU, adding the digits amplitude and | |
13 | // finding the maximum. Maximums are transformed in adc time samples. | |
14 | // Each time bin is compared to the trigger threshold until it is larger | |
15 | // and then, triggers are set. Thresholds need to be fixed. | |
16 | // Last 2 modules are half size in Phi, I considered that the number | |
17 | // of TRU is maintained for the last modules but final decision has not | |
18 | // been taken. If different, then this must to be changed. | |
19 | // Usage: | |
20 | // | |
21 | // //Inside the event loop | |
22 | // AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger | |
23 | // tr->SetL0Threshold(100); | |
24 | // tr->SetL1JetLowPtThreshold(1000); | |
25 | // tr->SetL1JetMediumPtThreshold(10000); | |
26 | // tr->SetL1JetHighPtThreshold(20000); | |
27 | // tr->Trigger(); //Execute Trigger | |
28 | // tr->Print(""); //Print results | |
