The distribution of galaxies in the Southern sky (left) and recessional velocity as a function of Tully–Fisher distance (right). In the right panel the Hubble constant relation with 73.3 ± 1 km s⁻¹ Mpc⁻¹ is shown (red line) and the scatter of the distances about this relation indicates the 1σ uncertainties of our distances is 19.5%.
