Composite radio (MGPS-2 at 843 MHz, Murphy et al. 2007, in red) and X-ray (XMM-Newton/MOS in the 2.5–4.5 keV band, in blue) image of RCW 86. The XMM-Newton/MOS image has been smoothed with a Gaussian of width 10′′. H.E.S.S. contours (Aharonian et al. 2009) are overlaid in white, as in Fig. 1. Triangles mark the RXTE pointing positions with the associated exposure times. The different ASCA/GIS regions for spectral extraction are delineated in green and labeled NE, SW and Inner (counts within the dashed circle were excluded), as in Bamba et al. (2000).
