25354ff4 19// Class for trigger analysis.
59264fa6 20// Digits are grouped in TRU's (Trigger Units). A TRU consist of 16x28
21// crystals ordered fNTRUPhi x fNTRUZ. The algorithm searches all possible
22// 4x4 crystal combinations per each TRU, adding the digits amplitude and
23// finding the maximum. Maximums are transformed in ADC time samples.
24// Each time bin is compared to the trigger threshold until it is larger
25// and then, triggers are set. Thresholds need to be fixed.
bb38a8fc 26// Usage:
27//
28// //Inside the event loop
29// AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
59264fa6 30// tr->SetL0Threshold(100);
bb38a8fc 31// tr->SetL1JetLowPtThreshold(1000);
bb38a8fc 32// tr->SetL1JetHighPtThreshold(20000);
33// tr->Trigger(); //Execute Trigger
34// tr->Print(""); //Print result, with "deb" option all data members
35// //are printed
