The SMD in a 640 × 640 Mpc cube, in comoving supergalactic coordinates. The density field is smoothed with a 3D Gaussian filter on a comoving scale of 10 Mpc. Seven isodensity contours ranging from 20%–80% of the maximum are illustrated with varying colors. Prominent objects with peak densities larger than half of the maximum density in the volume are listed. Thin vertical gray lines indicate the distance to the supergalactic plane. Acronyms denote the Southern Great Wall (SGW?) and the C29/C28 (C29?, C28?, C28b?) overdensities from Erdoǧdu et al. (2006), including clones of C28 in the ZoA.
