T0 Changes
¥Discovered the FB ORs missing in 30% of the
events.
¥Missing FB ORs were correlated with centrality
¥Determined that when FB Ors were moved to TDC 8, the
prompt signals were to early for the START of the TDC, and the TDC was stopping
on the reflection.
¥Added delay to the FB OR signals.
¥Vertex resolution improved to 2.5 cm for central
events.
