Object Cut Flows for ZGamma studies, (Z goes to electrons, or neutrinos).

Using the comparison datastream from data11_7TeV.00190300.physics_Egamma.merge.NTUP_SMWZ.f409_m1007_p716_tid536261_00 Comparing to M. Fisher's results, was able to find I was using an incorrect definition for z0 wrt PV for the electron cuts, and I was not using the D3PD tight value for photon candidates.

FTK Studies

Currently I am performing studies on the FTK track reconstruction efficiency for electrons produced with a Pt greater than 20 GeV. I am trying to see how the efficiency changes depending on the isolation of the track. We want to make sure we can still reconstruct high Pt electrons, even in a busy enivronment.
