a, The apparent size–apparent magnitude relation for low-surface-brightness objects in NGC 1052, using recent measurements from Legacy data23. Galaxies that are part of the trail are labelled with solid symbols. The thin solid line is a running median, with N = 7. The dashed line is a least-squares fit to the running median and has the form log re = −0.09(g − 20) + 0.87 kpc. Galaxies in the trail are typically larger than other galaxies of the same magnitude. b, Distribution of galaxies colour-coded by their location with respect to the least-squares fit. The largest galaxies in the group are preferentially located along the DF2–DF4 axis.
