Collision time and vertex resolution.
¥Use the fastest signal on either
side. This will produce a
multiplicity-dependent systematic shift towards shorter times.
¥Use the average time of all T0 signals on
either side. PMTs with large
signals will induce a systematic shift towards longer times.
¥Use the average time of all T0 counters
that fire within 250 - 500 ps of the fastest one.
¥Use the average of the largest number
of T0 counters that fire within
250 - 500 ps of the each other.
