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.
