¥After
correcting the delays of the T0 channels for the relative time delays obtained
by from the previous analysis, all vertex difference distributions (calculated
with respect to sensor T0N2 and T0P2) are aligned.
¥The
width of the vertex difference distribution is 3.2 cm (1s).
¥This
corresponds to a T0 collision time resolution of 100 ps (without slewing
corrections).
