Distribution of 2MRS galaxies with |b| ≥ 10°, in a volume-limited (top left) and a flux-limited (bottom left) sample to z≤ 0.024. Equal-volume and equal-Δz bins are used, respectively, to have reasonable numbers of events in each bin. The centre column contains the same plots for VCV galaxies and the right-hand column plots show the ratio of the number of VCV galaxies to the number of volume-limited (above) and flux-limited (below) 2MRS galaxies.
