- The T0 counters can be used to tag collision events for all but the most peripheral events.
- T0 efficiency is similar to the paddle efficiency(for all but the most peripheral events).
- The multiplicity distribution of the T0 counters for collision events peaks at 8 (all counters fire).
- The Esum(T0) counters is linearly correlated with the Esum(paddle). No evidence for saturation of either counter.
- Using T0 array for the vertex cut:
- The width (sigma) of Z from T0 = 2.3 cm
(without slewing corr.)
