¥Direct
determination of the time resolution of the T0 counters has been complicated by
the difference in response for d + Au compared to Au + Au.
¥For
Au + Au, the slewing parameters were optimized by looking at the time
difference between counters in the same array for good collision events.
¥This procedure fails for d + Au.
¥For
collisions, there appears to be at most one prompt T0.
