Quality of time-delay corrections.

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

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

•Results 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

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