Summary
- OBJECTIVE: I'm updating the reconstruction uncertainties to improve the particle-ID algorithms and support the kinematic fitting analyses.
- PLAN: I'm comparing the generated and reconstructed track parameters in the TOF, BCAL, and FCAL systems to determine the uncertainties.
- STATUS: TOF Uncertainties are below.
TOF Time Uncertainty
π- hits in both TOF planes
- Δt vs. x, y, average dE
- Fit the Δt distributions to Gaussian functions, σt's are fit below.
