Table 2: Summary of Vertex finding efficiency and vertex matching with events processed by Sept 2.  For the vpd, matched is defined as the 0 ranked PPV vertex is within 8 cm of the vpd vertex.  For the bbc, matched is defined as the 0 ranked PPV vertex is within 32 cm of the bbc vertex.

Table 3: Summary of Vertex finding efficiency and vertex matching with events processed by Sept 7.  For the vpd, matched is defined as the 0 ranked PPV vertex is within 20 cm of the vpd vertex.  For the bbc, matched is defined as the 0 ranked PPV vertex is within 60 cm of the bbc vertex.
