David's BCAL Photon Time Resolution Studies
- γ BCAL #sigma;t vs. dE (GeV):
Time Resolution Segmentation Ratio
- γ BCAL σt_1234 / σt_334 vs. dE (GeV):
- Fits to γ BCAL σt_1234 / σt_334 vs. θ in dE bins:
- Don't trust fits at low-θ, so linearly-interpolate between 12 and 16 degrees.
π+ BCAL Δβ vs p
Δβ = βp - βt = p/sqrt(p*p + m*m) - path/(c*TOF)
- X(2000) -> b1pi Events, π+ BCAL Δβ vs p, 334 Segmentation:
- X(2000) -> b1pi Events, π+ BCAL Δβ vs p, 1234 Segmentation:
