Left: difference map between the hard (1.5–10 keV) and soft (0.3–1.5 keV) band including counts of Ch 1, Ch 2, and Ch 3. Positive pixels (blue) depict a hard excess, negative pixels (red) a soft excess. Overlayed contours in black show H₂ 1–0 S(1) emission (Maccagni et al. 2016). Right: surface brightness profiles for the stacked map for the energy intervals 0.5–10 keV (black/circles), 0.3–1.5 keV (red/squares) and 1.5–10 keV (blue/triangles). The blue and red dashed lines show the Chandra PSF normalized to the hard (1.5–10 keV) and soft (0.3–1.5 keV) X-ray profile. The yellow shaded section marks the extent of the map on the left.
