Ratio between the integrated flux density and the peak flux density of isolated sources, i.e. sources with no other detections closer than 3× the beam size (47″), as a function of the distance from the pointing centre. Unresolved sources should have a value of around unity (red line), with resolved sources having higher values. The binned medians (blue crosses) go from 1.2 to 1.4. Since the majority of the sources in our catalogue is expected to be unresolved at this angular resolution, this is an indication of ionospheric smearing.
