XMM-Newton mosaics of the pointings toward HESS J1614−518, in a soft band (top panel, 0.3 keV–1.0 keV) and in a hard band (bottom panel, 3 keV–7 keV). Point sources were removed from the images. Contours denote the TeV surface brightness. The cross indicates the position of XMMU J161406.0−515225. The soft-band image is dominated by stray light from RCW 103 (northeastern arc feature). The hard-band image is dominated by a putative diffuse X-ray emission region coincident with the north component of the TeV source. The solid circle indicates an extraction area used to assess the spectrum for this diffuse component. Different background control regions (not shown) were used to estimate the systematic error induced by the background estimate.
