Event-of-the-Day

Today's event of the day is an event that my classification called simple clean, but MC classification says the event was scattering. Actually the only track through the detector at the time of the decay positron is a delta, but my MC classification prefers to call a track scattering if there is both scattering and deltas. My MC classification calls an event scattering if it changes direction and has hits on both sides of the muon stop. Todays event's decay positron was high angle enough not to leave the target. Since the angle of any delta track will have cosine theta outside of our fiducial volume, I won't worry about these.
