Detailed Description

Jet elements are the inputs to the Jet, ETmiss and ETsum triggers.

They are formed in two stages: 2x2 Trigger Towers (EM or Had) are summed in the PreProcessor The corresponding EM and Had towers are summed in the Jet/Energy Module In the simulation, both of these stages are performed in the TrigT1CaloSim::JetElementMaker algorithm.

As for most L1Calo outputs, the hardware can read out a variable number of slices of data. Hence JetElement stores its internal data in vectors, and can return an individal slice of data or the entire vector.
