Left column, lower panels: cGSMFs of our high-fidelity group galaxy subsample colour-coded by M_lum, as indicated in the legend. In panel (a) we use the LumB calibration factor, while in panel (b) we use the LumBfunc factor. Right column, lower panels: Same as the left but using the dynamical halo mas estimates with the MassA calibration factor in panel (c) and the MassAfunc factor in panel (d). Upper panels: Raw number of galaxies as a function of stellar mass in each sample, as indicated.
