Fig. 1
Energy-coded, three-color X-ray image of the field of view around HDE 228766 built from the EPIC data of the three observations. North is up and east is to the left. The red, green, and blue colors correspond to the photons in the energy ranges of 0.5–1.0, 1.0–2.0, and 2.0–8.0 keV, respectively. The individual images were exposure-corrected before they were combined. The bright source to the northwest of HDE 228766 is the Wolf-Rayet binary WR 138 (Palate et al. 2013).
