Procedure
- Reconstruct π(1600) -> b1π events with t-slope = 2.0 using both the 334 and 1234 segmentations
- Plot Δβ vs p for π+ candidates to see proton, π+ separation.
π(1600) -> b1pi Events
p vs. θ
- p vs. θ
π+ BCAL Δβ vs p
Δβ = βp - βt = p/sqrt(p*p + m*m) - path/(c*TOF)
- π(1600) -> b1pi Events, π+ Candidates, BCAL Δβ vs p
