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


  • Fit the Δt distributions to Gaussian functions, σt's are fit below.
σt vs. x
σt vs. y
σt vs. avg. dE


π- hit only in the horizontal plane

  • Δt vs. x, y, average dE
Δt vs. x
Δt vs. avg. dE


  • Fit the Δt distributions to Gaussian functions, σt's are fit below.
