The aim of the main algorithm of the present package (LArTTL1Maker) is the simulation of the LAr analogue trigger tower sums.

It includes correct allocation of cells to towers, pulse profile as a function of time, saturation, appropriate noise addition, pile-up.
The resulting signals are an input to the Preprocessor (which in turn performs digitization, filtering, bunch crossing id., noise suppression,...)
Since it needs hits, the simulation only takes "simul" datasets as input, NOT digitized datasets.

There is a second algorithm, LArTTL1Calib, which is meant to be run in standalone in order to perform the energy calibration of the Trigger Towers.
