Radio images of the inner radio structure of 3C 293 at four different observing frequencies: a) VLA B-array 22.46 GHz; the large cross in the image indicates the position of the western optical nucleus/the active radio core, while the small cross denotes the position of the eastern optical nucleus; b) VLA B-array 14.94 GHz; the ellipse and the circle indicate the two smaller apertures selected by Lanz et al. (2015) for the Chandra X-ray data analysis; c) VLA A-array 4.86 GHz; the labelling denotes the western lobe (WL), the western jet (WJ), the eastern lobe (EL), and the eastern jet (EJ); d) MERLIN 1.36 GHz reproduced from Beswick et al. (2002). In all panels, the contour levels given are (1, 2, 4, 8, ...) ×C mJy beam^-1, where the value of the C constant are provided in each image. For all images, the restoring beam is indicated by an ellipse in the bottom right corner.
