TOF

  • TOF hit reconstruction fixed by Simon.

Δβ

  • Δβ for all systems looks weird (e.g. BCAL):
Proton
PiPlus

Start Time

  • Source of Δβ problem: mismatch between the reconstructed track start time (t0) (typically SC hit time propagated to vertex) and thrown start time (0.0):
    • Note: If you use the thrown start time in the Δβ calculation, Δβ lines up at zero.
