25354ff4 18// Class for trigger analysis.
59264fa6 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
dab66d03 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.
64df000d 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.
bb38a8fc 25// Usage:
26//
27// //Inside the event loop
dab66d03 28// AliPHOSTrigger *tr = new AliPHOSTrigger();//Init Trigger
59264fa6 29// tr->SetL0Threshold(100);
bb38a8fc 30// tr->SetL1JetLowPtThreshold(1000);
dab66d03 31// tr->SetL1JetMediumPtThreshold(10000);
