VV124 (black filled circle) compared to other LG dwarf galaxies brighter than M_V /=  −7.0 in the M_V vs. logarithm of the half-light radius (lower panel) and M_V vs. central surface brightness (upper panel) planes. Different symbols are used for different morphological types, according to the classification criteria by Mateo (1998). Absolute magnitudes and half-light radii are taken from from Walker et al. (2010) and from Kalirai et al. (2010); when lacking in these sources they have been drawn from Mateo (1998). Surface brightness estimates have been taken from Mateo (1998), McConnachie & Irwin (2006), Martin et al. (2009), Zucker et al. (2007), Irwin et al. (2008), and Whiting et al. (1999), with this priority. All the values of surface brightness are corrected for extinction.
