Observed mass functions and Schechter (1976) function fits for galaxies in the different environments. Left panel: ICBS cluster regions (black crosses and solid line) and field (blue empty stars and dotted line). Right panel: EDisCS clusters (black crosses and solid line) and groups (red filled hexagons and dotted line). Mass functions are normalised using the total integrated stellar mass above the mass completeness limits. Errorbars on the x-axis represent the width of the bin. Errorbars on the y-axis are computed combining the Poissonian errors (Gehrels 1986) and the uncertainties due to cosmic variance and cluster-to-cluster variations. Shaded area represent 1σ errors on the Schechter fits. The labels at the top show both the observed and completeness-weighted galaxy numbers for ICBS, while for EDisCS only observed numbers are given. The K–S probabilities are also shown as percentages. The bottom left in-sets in each panel show the M and α Schechter fit parameters with 1σ errors. No significant differences are evident between the galaxy stellar mass distributions in different environments. For ICBS, similar results are also obtained comparing the cluster regions and the non-cluster regions (plot not shown).
