10// Class for trigger analysis.
59264fa6 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// 4x4 crystal combinations per each TRU, adding the digits amplitude and
14// finding the maximum. Maximums are transformed in ADC time samples.
15// Each time bin is compared to the trigger threshold until it is larger
16// and then, triggers are set. Thresholds need to be fixed.
bb38a8fc 17// Usage:
18//
19// //Inside the event loop
59264fa6 20// AliPHOSTrigger *tr = new AliPHOSTrigger();//Init Trigger
21// tr->SetL0Threshold(100);
bb38a8fc 22// tr->SetL1JetLowPtThreshold(1000);
bb38a8fc 23// tr->SetL1JetHighPtThreshold(20000);
24// tr->Trigger(); //Execute Trigger
59264fa6 25// tr->Print(""); //Print results
