VLBA images at 1.38 (left) and at 4.98 GHz (right). In each image, we provide the source name, the observing frequency, the peak brightness, and the first contour (f.c.), which is three times the off-source noise level on the image plane. Contours increase by a factor of 2. The restoring beam is plotted in the bottom left-hand corner of each image.
