Cutouts of the optical identification images centered on ERAGN ranked by their radio size in ascending order. Images are 50″ × 50″ (400 × 400 kpc at z = 1) indicated by the scale bar in the upper right corner. The centers of the radio sources are marked by red crosses, and their optical counterparts are marked by white boxes. North is up and east is to the left. The radio contours levels are 4, 16, and 64σ. The labels in the upper left are field name and radio id matched to spectroscopically confirmed or photometric galaxies.
