Figure 1: vpd vz - rank 0 PPV vz

Figure 2:vpd vz - rank 0 PPV vz

Figure 3:  Figure 1 fit with double gaussian where the mu = 0 for both, sigma 1 = 3, sigma 2 = 80

Figure 3 was fit from -200 to 200.  Narrowing this range did not change the shape of the function (or its miss around +/- 10) significantly

Figure 4:  Figure 2 with the same function as shown in figure 3.

Figure 5: vpd - vz for all ranked vertices.  All = sum rank0 + rank1 + rank2

Figure 6: Figure 1 fitted with 3 gaussians with amplitudes p0,p3,p6 all fixed at an average of zero.  The first gaussian has a sigma of 80, the second a sigma of 3 and the third was allowed to vary and it ended up at 25.
