Comparison of the geometric effective radius (left panels), and apparent magnitudes (central panels) between different sources from the literature. In grey are shown those samples in common with the SAURON galaxies and in colours those in common with our sample of dEs. The samples in common with SAURON (de Vaucouleurs et al. 1991; Pahre 1999; Jarrett et al. 2000; Kormendy et al. 2009) were analysed in Falcón-Barroso et al. (2011). In common with our dEs (T11 dEs) are Gavazzi et al. (2003); Geha et al. (2003); van Zee et al. (2004, GOLDMine database or GM hereafter, G03 and VZ04, respectively). The right panel shows the location of different samples of dEs on the FP fitted for the SAURON galaxies by Falcón-Barroso et al. (2011) and their 1σ scatter (solid and dotted lines respectively). With respect to the left and central panels we add the Fornax sample of dEs by de Rijcke et al. (2005, DR05) and the dEs from Coma by Kourkchi et al. (2012, K12). Those Coma dEs fainter than MV = −17 mag are plotted in grey.
