Same as the left panel of Fig. 6, but normalised by the total mass (dark matter + baryonic) in the field sample (magenta) and cluster sample (black). Per unit of total mass the cluster has a clear overdensity at all stellar masses we probe. Error bars show the 68% confidence regions from Monte-Carlo simulations (on the cluster data), or Poisson error bars (field data). In the left panel of Fig. 6 we provided an easier comparison of the shapes of the two SMFs.
