EVN 1.6 GHz images of (a) J131225.73 (undetected) and (b) J163650.43 (also undetected). The expected positions and errors in the maps represented by the crosses are provided in Fomalont et al. (2006) and Ivison et al. (2002) for (a) and (b), respectively. The maps are presented with contour levels −3 and 3× the rms noise. The white crosses on the maps are centred on the expected positions of the sources. For clarity, the map sizes correspond to the 2σ and 1.5σ uncertainties in the VLA positions for (a) and (b), respectively. In each panel the VLBI beam pattern is illustrated with a black ellipse.
