¥To
investigate the origin of the observed correlation we have looked at
correlations between T0 and Ckv counters.
¥In
this analysis we have looked at the same events (T0N = 1 and T0P = 1).
¥The
vertex is calculated on the basis of the time difference between the T0 and the
Ckv counters (T0P/CkvN and T0N/CkvP) and compared to OctDeVertex.
