Prediction of the fractional Hubble uncertainty as a function of direction within 60 h⁻¹ Mpc around the observer. As can be seen, the fractional Hubble uncertainty is highly structured on the sky, with large-scale coherent bulk flows. The dominant red central region points towards the direction of Perseus Pisces. These effects need to be accounted for when inferring the Hubble parameter from data of the nearby universe.
