Same as Fig. 3 for Pseudo-Ring attribute. As this is a low surface brightness feature, high-contrast pseudo-rings are preferentially shown here. The galaxies shown in the bottom row are the latest type galaxies (Sbc, Sb, Sb, Sbc resp.) with attributes values of 0.25, 0.5, 0.75, 1.0 respectively (for a fair comparison, an Sbc galaxy is also shown in the bottom row for attribute value 0).
