TOF
- TOF hit reconstruction fixed by Simon (only the energy of the last hit was saved, rather than the sum).
Δβ
- Δβ for all systems looks weird (e.g. BCAL):
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.
