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
Δt vs. x
Δt vs. y
Δt vs. avg. dE


  • Next, the above histograms were fit to Gaussian functions, and the σ's are fit below.
σt vs. x
