Half-light radius r1/2 in observed (angular) units as a function of total flux Fν,tot at 12 μm. Type 1 sources are shown as blue stars, type 2 sources with red diamonds. The two colored lines denote the expected source sizes using the scaling and normalizations from NGC 1068 (green line) and Circinus (red line) as a reference. The two red circles denote the sizes of the scaled-down versions of the bright sources. They are compatible with the actual sizes of the faint targets, showing that the source sizes indeed scale with . However, the relation is dominated by large scatter, especially when including the limits. The statistical errors of the MIDI size measurements are smaller than the symbols and therefore not shown.
