Further Preshower Plots

Figures 1, 3, and 5 show plots involving geant preshower energy deposition (i.e., with no calorimeter simulation applied): for each tower-only cluster the preshowers in front of it are identified and their geant energies summed and plotted in the upper left of each figure.  The upper right shows the geant energy plotted against the reconstructed preshower energy (calculated in the same way but with energies obtained from StEmcSimulator), and the lower left shows the geant energy vs. eta.  Figures 2, 4, and 6 have the same plots as on the previous blog post (reconstructed preshower energy, energy-weighted preshower eta and phi, and reconstructed preshower energy vs. tower energy), with the addition of reconstructed preshower energy plotted vs. eta.  Figures 1 and 2 show these plots for gammas, figures 3 and 4 for piminus, figures 5 and 6 for electrons.  All energies are plotted in units of GeV.  For all particle species, the seed tower threshold was 1 GeV and the cluster threshold was 4 GeV.
