The Aquila sub-field is shown as a column density image with a 37′′ resolution (left, Könyves et al. 2010), an accumulated clean combined detection image containing spatial scales of up to 80′′ (middle), obtained by summing up the single scales ℐ_Dj   C in that range, with the 500 μm ellipses of all detected sources overplotted. Also shown is the clean background ℐ_λO   CB (right) at 500 μm. For better visibility, the values displayed in the panels are somewhat limited in range; the color coding in all panels is a function of the square root of column density and of intensity in MJy/sr.
