Exposure map corrected EPIC combined image of A 4059, in units of number of counts. The two datasets have been merged. The cyan circles show the detected resolved point sources that we excise from our analysis. For clarity of display the radii shown here are exaggerated (excision radius = 10′′, see Appendix A.2). The white annuli show the extraction regions that are used for our radial studies (see text and Sect. 5).
