Flows away from the edges of the Arrowhead Supercluster toward alternatively the Laniakea, Perseus–Pisces, and Coma basins of attraction. The Arrowhead is bounded by voids on the far side from Laniakea and in the directions above and below in SGZ. The orientation of the plot is given by the three arrows located at the position of the Milky Way with lengths of 1000 km s⁻¹: red arrow toward +SGZ, green arrow toward +SGY, and blue arrow toward +SGZ.
