VLBI images at 8.4 GHz (natural weighting for insets of 0235−618 and 0308−611 and all other images; tapered to 10% at 100 Mλ for main panels of 0235−618 and 0308−611). Restoring beams are shown in the bottom left corners. The color scale covers the range between the mean noise level and the maximum flux density (1759−396, see Table 2 for image parameters). Contour lines start at 3σ_rms and increase logarithmically by factors of 2. The array is given in the bottom right corner: PA: Parkes, AT: ATCA, MP: Mopra, HO: Hobart, CD: Ceduna, HH: Hartebeesthoek, TC: TIGO, TI: Tidbinbilla (70 m), TD: Tidbinbilla (34 m), WW:Warkworth
