Trigger towers are the inputs to all other parts of the calorimeter trigger. They are formed by analogue summation of cells (represented in simulation by LArTTL1 and TileTTL1 objects). The L1Calo PreProcessor digitizes these, performs Bunch-Crossing IDentification, final calibration and reduction to 8 bit words.

The TriggerTower class represents the output of the PreProcessor. Each TriggerTower object actually contains information from a pair of trigger towers, one EM and one Hadronic, sharing the same eta, phi coordinates. This is convenient for algorithm emulation, though it does not represent the readout arrangement.

For each tower, the TriggerTower contains the final ET (LUT output) as well as a vector of ADC data (at 25ns intervals) from which it was formed, plus error flags and raw BCID output. As the PreProcessor readout can read variable numbers of slices of all of these data, the internal storage is in std::vectors, and methods exist to return all slices as well as just the data corresponding to the triggered crossing.
