Top left panel: SMF of cluster galaxies within R ≤ 1000 kpc from the cluster centres. Black points: total galaxy population. Blue and red data points: population of star-forming and quiescent galaxies, respectively. Small horizontal offsets have been applied compared to the black points for better visibility. The open circles mark points below the 80% mass completeness limit, and even though we perform an incompleteness correction these are not used in the fitting. Top right panel: SMF of co-eval field galaxies from the COSMOS/UltraVISTA survey (1.0 < z < 1.4). The best-fitting Schechter functions are included in both top panels. Lower panels: relative fraction of quiescent galaxies as a function of stellar mass in the different environments.
