Chandra broadband (ObsID: 28148, 0.5−7 keV) image of UGC 2369S. The cores are fitted with three PSFs generated by CHART. We fix the relative displacement between these three cores to the value found in the MUSE observation. Only the northern core has an unresolved pointlike structure. We note that even for object 3, a significant amount of flux is generated in a diffuse star-forming region.
