The relation between size and V-band magnitude for our pz sample (black circles, with error bars showing the 10th to 90th percentile range). We compare our size and V-band magnitude relation with the results from the dwarf galaxy literature: Milky Way dSphs (red triangles; Brasseur et al. 2011), Andromeda dSphs (orange crosses; Brasseur et al. 2011), dwarf galaxies in the Local Group (blue squares; McConnachie 2012), Virgo dEs (orange circles; Toloba et al. 2012), satellite dwarf galaxies reported by the ELVES project (gray dots; Carlsten et al. 2022), and Andromeda dwarf galaxies from Doliva-Dolinsky et al. (2023, stars). The dashed green lines show the surface brightness limit in units of magnitudes per square arcsecond.
