• Attempting to understand the ATLAS software by plotting things from the top group’s common ntuples. • Used the default LVL 1 trigger information to look for electrons by plotting the number of ecal ROIs for each event.
• Then made further requirements: 1. The ROI had E > 20 Ge. V. 2. The energy in the surrounding ecal trigger towers is < 3 Ge. V. 3. The energy in the hdcal core and isolation trigger towers is <2 Ge. V. • • 2 and 3 ensure that the ROI represents an isolated particle. The results compare well with the number of electrons from truth.
