Point source fraction fp as a function of total flux for all observed objects. Type 1 AGNs are marked with blue stars, type 2 AGNs with red diamonds. The two upper limits are unsuccessful fringe tracks in otherwise stable nights. The green curve denotes the observational limit which is given by the minimum unresolved flux required to track a source. A green box denotes objects of model case 1 (resolved Gaussian + point source).
