Caption: Figure 6.
Similar to Figure 4, but for BCG-to-total stellar mass ratio. For a given cluster mass bin, the ratio decreases with time, because of the dramatic differences in the rates of growth between Mbcg and Mstar,tot. Also, at a given redshift, the BCG dominance decreases with cluster mass.
