X-ray (XMM-Newton, left panel) and optical (PanSTARRS, right panel) images of the central cluster region within 0.5 R₅₀₀ of Abell 1763. Crosses and squares mark XMM-Newton and Chandra detections, respectively. Sources with a flux lower than the threshold applied in Sect. 2.2 are ommited. Chandra detects a point-like X-ray source in close proximity to the brightest cluster galaxy (BCG) and at concordant redshift with the cluster. All other sources detected by either telescope or both are discarded due to their redshift or extent, as described in Sect. 2.2.
