T0 Vertex Studies:
The best way to determine time resolution.

•The collision time, obtained from the T0 array, is equal to

•

•tcol = (tT0N + tT0P)/2

•

•The resolution of the collision time is equal to

•

•sTcol = sT0/√2

•

•The vertex position, obtained from the T0 array, is equal to

•

•zvertex = c (tT0N - tT0P)/2

•

•The resolution of the collision vertex is equal to

•

•svertex = c sT0/√2 = c scol

•

•We use svertex to determine sTcol.
