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)
Proton
PiPlus
  • 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.
Proton
PiPlus
  • Δt (treconstructed - ttrue) vs. p

PiPlus

BCAL

  • Δβ (βt - βp) vs. p
    • Δt & Δp are OK, it looks like the problem is with the start time (at least for the pions) (set to weighted average of start counter hit times instead of RF bunch times).
