Magnitude distributions of all sources in OmegaWINGS (red histograms) and WINGS (shaded grey histograms) for all 45 OmegaWINGS fields. WINGS MDs are renormalised to match the number of bright (16 <V< 21 mag) objects in OmegaWINGS LFs. The vertical lines show the overall OmegaWINGS 50% and 80% completeness level (see Sect. 5.3). The label in each panel indicates the seeing in B- and V-band images, in arcseconds.
