Figure 1: Vz for the different index vertices. We see that there are a small fraction of "real" vertices that are not the highest ranked vertex. One can also see the pile-up vertices in the peaks every 10 cm or so.
Figure 2: (Left) Vz for all index 0 vertices. (Right) Vx and Vy for all index 0 vertices.
Figure 3: (Left) Vx and Vy for index 0 vertices with 199 < Vz < 202. (Right) Vz for the index 0 vertices, for all in black (same as Figure 2) and for Vertices with |Vx|<1 and -3 <Vy < -1 in red. We see that all of the vertices in the target z range are also in the target Vx-Vy range.
Figure 4: (Left) Number of EPD Mips in the inner EPD region (same acceptance as the BBC) versus the number of tracks used to reconstruct the index 0 vertex with the target selections (199 < Vz < 202, |Vx| < 1, -3 < Vy < -1). (Right) Number of tracks used to reconstruct the index 0 vertex versus the number of tracks matched to the BEMC.
Figure 5: Number of tracks used to reconstruct the index 0 vertex versus the number of global tracks.
Figure 6: (Left) Number of tracks used to reconstruct the index 0 vertex versus the the BBC rate. We see little evidence of pile-up corruption here. (Right) Number of global tracks versus BBC rate. We see more global tracks with higher rate, though this pile-up does not seem to effect the vertex reconstruction.
