VLA flux density images of 0954+556 at kpc scale. The contours are drawn at –1, 1, 2, 4, 8, …, of the first contour level (3σ_rms). The synthesized beams are plotted in the bottom left corner of each image. In the top left panel, the red circles overlapping the contours present the results of modelfit. In the top middle panel, the 5 GHz image shows a weak counter-jet. To better reveal the weak counter-jet, the 5 GHz image was restored with a circular beam of 900 mas, as shown in the top right panel.
