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
- Hits in both TOF planes, Δt vs. X, Y, average dE
- Next, the above histogram was fit to Gaussian functions, and the uncertainties are plotted with the points below. The function shows the FCAL shower energy uncertainty as currently used in the reconstruction code.
