Left panels: the distribution of galaxies (grey dots) in the sky, for the two superclusters, SCl 061 (upper row) and SCl 094 (lower row). Circles mark the location of groups with at least 30 member galaxies, and the size of a circle is proportional to the size of a group in the sky. The numbers show Abell clusters. The middle panels show the fourth Minkowski functional V₃, and the right panels the shapefinders K₁ (planarity) and K₂ (filamentarity) for a supercluster. The morphological signature in the K₁ − K₂ plane is parametrically defined as K₁(mf) and K₂(mf). The sizes of open circles are proportional to the value of V₃ at a given mass fraction mf. They show the change of the clumpiness with the mass fraction together with the changes in the morphological signature. The Abell clusters in the supercluster SCl 061 (upper row) are 1 – A1620, 2 – A1650, 3 – A1658, 4 – 1663, 5 – 1682, 6 – 1750, 7 – 1773, 8 – 1780, and 9 – 1809. The Abell clusters in the supercluster SCl 094 (lower row) are 1 – A2067, 2 – A2065, and 3 – A2089.
