Distribution of the Visible Dust (left) and Dust Dispersion (right) attributes for the 4458 and 1905 EFIGI galaxies for which these attributes are defined (same presentation as in Fig. 5). The left panel shows the large amounts of dust for early and intermediate spiral types (Sa to Scd), with a peak for Sb galaxies, and the lower values for late spiral (Sd to Sm) and Im types. The right panel shows the increasing Dust Dispersion for spiral galaxies of later type.
