// Class for trigger analysis.
-// Digits are grouped in TRU's (384 cells? ordered fNTRUPhi x fNTRUEta).
-// The algorithm searches all possible 4x4 cell combinations per each TRU,
-// adding the digits amplitude and finding the maximum. Maximums are compared
-// to triggers threshold and they are set. Thresholds need to be fixed.
-// Last 2 modules are half size in Phi, I considered that the number of TRU
-// is maintained for the last modules but decision not taken. If different,
-// then this must be changed.
+// Digits are grouped in TRU's (Trigger Units). A TRU consists of 384

+// and nxn (n is a multiple of 2) cell combinations per each TRU, adding the
+// digits amplitude and finding the maximum. If found, look if it is isolated.
+// Maxima are transformed in ADC time samples. Each time bin is compared to the trigger
