9 | // Class for trigger analysis. | |
10 | // | |
11 | // -- Author: Gustavo Conesa & Yves Schutz (IFIC, SUBATECH, CERN) | |
12 | // Digits are grouped in TRU's (Trigger Units). A TRU consist of 16x28 | |
13 | // crystals ordered fNTRUPhi x fNTRUZ matrix. The algorithm searches all possible | |
14 | // 2x2 and nxn (n multiple of 4) crystal combinations per each TRU, adding the | |
15 | // digits amplitude and finding the maximum. Iti is found is maximum is isolated. | |
16 | // Maxima are transformed in ADC time samples. Each time bin is compared to the trigger | |
17 | // threshold until it is larger and then, triggers are set. Thresholds need to be fixed. | |
18 | // Usage: | |
19 | // | |
20 | // //Inside the event loop | |
21 | // AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger | |
22 | // tr->SetL0Threshold(100); | |
23 | // tr->SetL1JetLowPtThreshold(1000); | |
24 | // tr->SetL1JetMediumPtThreshold(10000); | |
25 | // tr->SetL1JetHighPtThreshold(20000); | |
26 | // .... | |
27 | // tr->Trigger(); //Execute Trigger | |
28 | // tr->Print(""); //Print data members after calculation. | |
