Comparing Spec Vertex with T0 OR Vertex
Comparing Spec Vertex with T0 OR Vertex
¥The
T0 OR Vertex is obtained from the OR information obtained using TDC 8:
T0 OR Vertex = 29.979*((tExtra[19] -
311.87) - (tExtra[20] - 302.65))/2.0
¥
¥The vertex resolution is 4.8 cm (1 s).
¥This implies a resolution of the T0 Ors of 225 ps (1 s).
This resolution is most likely dominated by the alignment accuracy.
