Top panel: cluster data points for the different galaxy types within R₅₀₀. The curves show a basic quenching model inspired by the formalism presented in Peng et al. (2010), with the UltraVISTA SMF in the redshift range 0.5 <  z <  0.7 g point. Bottom panel: difference between the data (total distribution of quenched galaxies) in the cluster compared to the prediction from the model. This suggests a relative removal/destruction of low-mass galaxies and the expected build-up of BCGs.
