Quality of time-delay corrections.

ĄThe quality of the time-delay corrections can be examined by comparing the T0 vertex with the silicon vertex.

ĄAny drifts in the delay time will change the position of the T0 vertex.

ĄResults over a 2.5 month period:

Run 8045:

dZ = +0.417 cm

Run 8963:

dZ = -0.035 cm

Run 9174:

dZ = -0.033 cm

dZ = T0 Vertex - Silicon Vertex

ĄThese results suggest that the calibration procedure is stable to better than 62 ps.
