¥Observed poor T0 vertex
resolution (> 15 cm) as soon as silicon vertex information was available and
that OR signals were late compared to PR03.
¥Problem due incorrect
orientation of cable between discriminator and TEQ.
¥Change in cabling moved
Ors forward by 75 ns.
¥Discovered problem with
TDC 17 (or slot 17).
¥Moved ORs to TDC 8. Resolution improved to 8 cm.
