   NED object is Cygnus A; Reference is 1984MNRAS.209..851A

   Figure la. Full-resolution 2.7-GHz map. Contour levels: 0.2, 0.4, 1.0, 3.0,
 5.0, 7.0, 9.0, 11.0, 13.0, 15.0, 17.0, 19.0, 21.0; dashed: 25.0, 30.0, 40.0,
 Jy per beam. The inset shows two south to north cross-sections through the
 bridge between the Sf lobe and the central component. The marks are at
 intervals of 250 mJy per beam. Residual small phase errors are responsible for
 the lower dynamic range (600:1) near to the hotspots than the centre of the
 map where the sensitivity is about three to four times higher. The coordinates
 are for 1950.0 in all of the maps.
