Chandra 0.7 − 2 keV (left panel, color images) and SDSS r-band cutout images (right panel, greyscale images) showing the individual clump candidates (white, irregular-shaped regions) and their environment within a 200″ × 200″ area. The Chandra images are smoothed with a Gaussian of a radius of 6 to accentuate the X-ray excess. Filled black ellipses represent excluded wavdetect sources, while the filled red circle at the bottom left of each Chandra image marks the local minimum size of PSF. As most of the clump candidates overlap with multiple SDSS galaxies (green circles), possible physical connections must be addressed to isolate genuine clumps (Sects. 3.1.1 and Appendix A).
