So I found a run that did not appear to have this shoulder present in it(1665)(Figure 2) and I compared its reconstructed vertex to the new runs (2107)(figure 1), you can see this in the first two figures.
Next I plotted the reconstructed vertex vs t2, fig 3 is for run 1665 and fig 4 is for 2107. notice that run 2107 seems to have was looks to be a ghost image toward the left of the plot that is not present in the 1665 plot.
I then also plotted the reconstructed vertex vs t6 (fig 5 is run 1665)
and fig 6 is run 2107. Again there is this double image present in 2107
and not in 1665.
