18 | // Class for trigger analysis. | |
19 | // Digits are grouped in TRU's (Trigger Units). A TRU consist of 16x28 | |
20 | // crystals ordered fNTRUPhi x fNTRUZ. The algorithm searches all possible | |
21 | // 2x2 and nxn (n multiple of 2) crystal combinations per each TRU, adding the | |
22 | // digits amplitude and finding the maximum. If found, look if it is isolated. | |
23 | // Maxima are transformed in ADC time samples. Each time bin is compared to the trigger | |
24 | // threshold until it is larger and then, triggers are set. Thresholds need to be fixed. | |
25 | // Usage: | |
26 | // | |
27 | // //Inside the event loop | |
28 | // AliPHOSTrigger *tr = new AliPHOSTrigger();//Init Trigger | |
29 | // tr->SetL0Threshold(100); | |
30 | // tr->SetL1JetLowPtThreshold(1000); | |
31 | // tr->SetL1JetMediumPtThreshold(10000); | |
