Each set of plots were made from 5000 events, with a flat pt distribution between 5 and 40 and a flat eta distribution between -.2 and 1.2.  Clustering was done by finding seed towers (towers with energy > 1GeV) and then finding the highest-energy 2x2 patch of towers containing the seed tower.  If this 2x2 patch had energy > 4GeV, it was saved as a cluster.  The geant QA plots are shown first, then the clustering distribution plots, and then the plots with the event-level information (the number of seed towers and clusters).
