Same as Fig. 3 for Multiplicity attribute. Because EFIGI galaxies with an attribute value of 0.25 are all cD galaxies, we only display these types in the right panel of each line. As cD galaxies have an extended halo and lie in dense regions of clusters, they have both high Multiplicity attribute and low to moderate Contamination. Note that although PGC0004906 (left panel of central row) has 2 neighbouring galaxies, these are too faint in comparison to the central galaxy to be accounted for in the Multiplicity.
