Left: μ₀–M_V relation for the photometric parameters of the known Local Group dwarfs (gray dots, McConnachie 2012) and the new candidates (red squares). Indicated by the thin line is the assumed completeness boundary (Sect. 3) at 7 Mpc, which is bracketed by lines corresponding to assumed distances of 5 Mpc and 10 Mpc  to take care of the expected distance spread. Right: same data and color-coding, but for the log r_eff–M_V relation.
