Fraction of red and early-type galaxies in the Virgo (magenta) and Fornax (green) clusters. The lines show the red or early-type fraction according to different definitions. The W+11 line corresponds to a linear demarkation line as a function of total magnitude bluewards of the red sequence from Weinmann et al. (2011). The second, dash-dotted line is for the early-type fraction according to the morphological classification. The RS-σ line corresponds to a split between the red and blue galaxies along the red sequence (RS) traced by running means minus the 1σ scatter in the running bins of 1 dex width (see the dashed lines in Fig. 2). The Fornax cluster has, by all measures, a higher fraction of early-type and red galaxies throughout almost the whole range of stellar mass.
