Map of galaxies in the vicinity of NGC 253 in the supergalactic coordinates. Left-hand panel: XY-projection on the supergalactic plane, while right-hand panel: edge-on view of the Local Supercluster ‘pancake’. The sizes and colours of the dots correspond to the absolute B-band magnitude and morphology of galaxies, following the keys at the top. The line segments indicate uncertainties in the distance estimations. Large circles around NGC 253 mark the virial zone, R₂₀₀ ≈ 190 kpc, and the zero velocity surface, R₀ ≈ 700 kpc. The magenta symbols indicate the expected position of the discovered galaxies.
