The naturally weighted 1.6-GHz (left column) and 5-GHz (right column) VLBI images of the quasars. The image parameters (peak brightness, lowest contour level corresponding to ~3σ image noise, restoring beam size, and orientation) are listed in Table 3. The full width at half maximum (FWHM) of the Gaussian restoring beam is indicated with an ellipse in the lower-left corners. The positive contour levels increase by a factor of 2. The coordinates are related to the brightness peak of which the absolute position is given in Table 4.
