Caption: Figure 3.

Cartoon similar to Figure 2, illustrating a more complex situation and the option to excise the footprint of extended objects if the sources within such footprints are excluded from the extracted source sample. The areas of the light-blue shaded bins are included in the integration, but if extended objects (larger than a given size) are excluded (the red ellipse represents a hypothetical galaxy), then the bins whose centers fall within their footprint (outlined with thick black boxes) are not counted in the area integration.
