Photon and friends
by Whoandwhatitis moderator
The yellow blob in the green ring is a series of deposits of energy in the electromagnetic calorimeter. These may be part of the large yellow indicator that overlays the muon detector ring (blue). The height of this yellow block indicates the amount of energy the photon carries.
It's possible that other charges particles deposited energy in the calorimeter in this same area.
That photon was one of the most energetic that I've seen in this project - I'd say it's in the 90th-percentile.
I'd say this image is definitely #weird because there is very little energy in the rest of the detector aside from this yellow blob in the green ring. It's definitely a nice one!
