Two-dimensional projection of a ~2.1h^-1 Mpc deep test field for DALE computation. The red line segments show the local direction of anisotropy calculated in the positions of galaxies, shown with black dots. There are 662 galaxies; the neighbourhood radius ν = 7.0h^-1 Mpc. The signs of direction vectors are random, which results from the definition of our method. Several directions in a single point are due to overlapping galaxies in projection.
