Testing for the existence of the DoS. The behaviour of ℛ for each view of the MW, given by the Galactic longitude of the normal vector for each plane-fit. ℛ = N_in/N_out is the ratio of the number of satellites within 1.5 × Δ_min (Δ_min = 28.9 kpc), N_in, to those further away from the best-fit line, N_out, calculated for all 24 known satellites, as well as for the fits to the 11 classical and the 13 new satellites separately (taking their respective rms heights as the relevant Δ_min). The disc-like distribution can be clearly seen as a strong peak close to l_MW = 150°. Note that the position of the peaks are close to each other for both subsamples separately. This shows that the new satellite galaxies independently define the same DoS as the classical satellite galaxies.
