Best-fit double Schechter function parameters of the GSMFs shown in Fig. 5, using the same colour-coding. The x-axes distinguish between central, satellite, and ungrouped galaxies; within each sample, the three ticks correspond to the total (T), star-forming (SF), and passive (P) subsamples. The black, blue and red horizontal bands show the results for the full parent, all-star-forming and all-passive samples, respectively, taken from Fig. 4. These reference lines are meant to be compared only with the T, SF, and P values in each subsample, respectively. Corresponding corner plots illustrating the correlations among fitted parameters are provided in Figs. A.4 and A.5.
