EM37 - single photons
(Et-E)/Et HISTOS for 6 different cuts in eta

NOTES: It is interesting to observe that the reconstruction appears to work really well for eta>0.5. This doesn't work at all for higgs samples (e.g., see this). However, I believe this phenomenon is due to the fact that all bad events were removed during the production of the CBNT (since I didn't produce it, I am not sure).
