Event Selection

BETA2 Event
Cluster is not a noisy block
Cherenkov TDC cut
Energy cut (specified, however, it is on the cluster's uncorrected energy. I have to fix this.)
Phi cut -0.4 to 0.4

With the additional Cherenkov ADC cut, 0.5 to 1.5 electrons, the asymmetry appears to always increase showing that this cut is removing many background events. See green points

Cherenkov ADC cut always increases the asymmetries with the low energy cut.
Low energy cut has more background dilution (coming mostly from the tracker).
The higher energy cut is less diluted due to the energy dependence of the background.
There are runs which I do not have an "offline" target polarization and am not showing an asymmetry.

I have yet to replay full statistics for some runs and I should update them.

Conclusion

Cherenkov ADC cut is important for removing background.

Simulation

When calculating the radiation length for the ammonia target I get roughly 7.8 percent. While I have seen numbers like 4.6 percent. What should I use in the wiser code? If I follow the wiser code recommendation I would use a number closer to 9 percent.
