Binned, exposure-uncorrected X-ray image of AM72 with superposed adaptively smoothed X-ray contours measured on the exposure-corrected image. The cluster is morphologically complex, with two clumps aligned along the north–south direction, also traced by the distribution of spectroscopic members in Fig. 6. Spectroscopy confirms that this is a single system rather than two structures projected along nearby lines of sight. The bright X-ray emission to the West corresponds to a background cluster. The extreme faintness of the cluster X-ray emission and the presence of several point sources prevent the contours from fully tracing the extended emission.
