A comparison between the properties of the dwarf galaxy candidates studied in this work, the first DGSAT results (Javanmardi et al. 2016), and the known dwarf galaxies of the Local Group (McConnachie 2012). Top: effective radius in pc versus logarithm of V band luminosity in L_⊙. Middle: V band surface brightness in mag/arcsec² versus effective radius in pc. Bottom: V band surface brightness in mag/arcsec² versus absolute V band magnitude. The V band quantities were obtained by transforming r band magnitudes to V magnitudes using Fukugita et al. (1996).
