Fig. 18.
Top plot: star-galaxy separation using the 0p7 and 1p0 GAAP magnitudes. The objects shown in gold form a sequence along which both apertures yield consistent fluxes, indicating that they are unresolved. Bottom plot: g − r, r − i colour–colour diagram for the same sources, confirming that these sources are stars.
