- Model resolutions using MC reconstruction
- Use old geometry (no summing, inner segments SiPMs, outer segments FM pmts)
- Optimistic, since summing will likely degrade performance. Dan is implementing the new scheme and will rerun programs when complete.
- New normalization comes from Andrei, corresponds to 165 photons/MeV in fiber/side compared to nominal 75 photons/MeV in fiber/side.
- Results show that a factor of 10 increase in dark current changes resolution sigma by about a factor of 2.
