MOST (green) and ATCA 20 cm (blue) radio contours and Chandra X‐ray (red) contours of the northeast X‐ray peak overlaid on the CTIO 0.9 m R‐band image of A3128. The beam size of the 20 cm image, which is ﹩15\farcs 0\times 9\farcs 95﹩ (﹩\mathrm{P}\,.\mathrm{A}\,.=-20^{\circ }﹩), is shown as the black ellipse in the lower right corner of the figure. The ATCA contour levels are 1, 2, 4, 8, and 16 mJy beam⁻¹. The MOST contours are 2, 3, 4, 7, 10, 20, and 40 mJy beam⁻¹, while the beam size is ﹩54^{\prime \prime }\times 43^{\prime \prime }﹩ (﹩\mathrm{P}\,.\mathrm{A}\,.=0^{\circ }﹩). The Chandra contours are 0.14, 0.16, 0.22, 0.32, 0.45, 0.63, 0.85, 1.10, 1.39, 1.73, and 2.10 counts s⁻¹ in the smoothed image.
