Blue = PU2
Green = PU20
Red = PU40
Sigma vs Eta with PU 2 20 40 60
This plot was generated by taking the two superclusters which are closest to the two generated electrons from the dielectron gun. A ratio is taken of the energy of the supercluster over the energy of the matched electron. The width of this ratio represents the resolution of the reconstruction in ECAL. The high side tail is shown to increase as a function of #eta. the small collection of events at 0 represent very low energy superclusters that were matched to electrons yielding a ratio close to 0 GeV.
