   Figure 2. The brightness distribution at 1.4 GHz from the Half-Mile
 telescope. A point source of flux density 1.08 Jy has been removed from the
 position of the hotspot marked by a cross, but the structure of the
 surrounding regions is still considerably distorted. Contours are -10
 (dashed), 10, 20, 30, 40, 50, 60, 70, 80, 90, 120, 150, and 180 mJy per beam.
