ASKAP 1 GHz radio continuum images of the radio galaxies shown in Fig. 1 overlaid on DSS2 R-band images. Top left: F2, top right: N1, middle left: F3, middle right: F1, bottom left: S1, bottom right: S2 and S3. The radio contour levels starting at 3σ are typically 0.012, 0.025, 0.05, 0.1, 0.25, 0.5, 1, 2.5, 5, 10, 25, 50, 100, 250 and 500 mJy beam⁻¹, except for F1-F3 where a 0.006 mJy beam⁻¹ contour is added, and N1 where the 0.012 mJy beam⁻¹ contour is omitted.
