Here is a preliminary color offset plot. Zero offset corresponds to
center of red sequence; objects bluer than RCS have negative offsets.
If you extrapolate the mean number per large negative (blue) color
offset bin into the range where the RCS lies, the excess is still
significant. The RCS typically lies in the range -0.1 < Delta Color <
+0.15. So this corroborates the spectroscopic plot as well. I will
generate precise integrals over the weekend.
