Event Selection

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

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.

  1. Reproduce marks, usings mark's inputs
  2. Divide the detector in two.
  3. In one week get parallel asymmetries.
  4. Cherenkov paper.
