Angular sizes of the extracted sources. Left panel: probability density distribution of the circularized FWHM of the sources. Red and blue bars include sources detected within the near sample and the far sample targets, respectively (see Sect. 2). Right panel: distribution of the ratio between the estimated angular size of the source and the map beam size (both in circularized form), providing a resolution-independent estimate of the source sizes. The vertical dashed black line marks the median value of 1.15 for the ratio.
