T0 Vertex Studies:
Comparing Spec Vertex with Oct dE Vertex
¥Our studies of T0 vertexing were carried out using run 10920.
¥Run 10920 is a long run, with about 63 sequences, taken on 1/28/03 with a B+ field.
¥We have used Spec Vertex to compare the silicon vertex with the T0 vertex. and selected only events for which the Spec Vertex is located between ±20 cm.
¥For events with a valid spec vertex the Oct dE vertex and Spec Vertex agree within a resolution of 1.0 cm (1 s).
