VLA B-array 1.36 GHz map of the large-scale structure of the radio source 3C 293, hosted by the galaxy UGC 8782. The rectangle inside the central core region corresponds to the frame of Fig. 1. The small circle and three ellipses denote the regions where the X-ray emission was detected and modelled by Lanz et al. (2015). The restoring beam (10″ × 10″) is indicated by a circle in the bottom right corner.
