TOF
- VERY FEW hits reconstructed in TOF.
- TOF reconstruction (DTOFHit factory) requires hits in both the "North" and "South" PMTs of a scintillator to be > 1 MeV.
- TOF Hit North Energy vs. p (Reconstruction energy threshold cut at 1 MeV)
- TOF Hit South Energy vs. p (Reconstruction energy threshold cut at 1 MeV)
FCAL
- Δβ (βt - βp) vs. p
- Δβ offset is accounted for by time offset below.
- Δt (treconstructed - ttrue) vs. p
BCAL
- Δβ (βt - βp) vs. p
- Δt & Δp are OK, the problem is with the start time (set to weighted average of start counter hit times instead of RF bunch times).
- PID routine is OK, compares against RF times.
- Δt (treconstructed - ttrue) vs. p
