Top left: XMM-Newton EPIC image of MCSNR J0512−6707 in false colour with RGB corresponding to 0.3–0.7 keV, 0.7–1.1 keV, and 1.1–4.2 keV. The image is overlaid with [S ii]/Hα contours with the lowest level corresponding to [S ii]/Hα = 0.4, and the remaining levels at 25%, 50%, and 75% of the maximum above this level. Top right: continuum subtracted MCELS image of MCSNR J0512−6707 with Hα in red and [S ii] shown in green overlaid with 0.3–0.7 keV contours. The lowest contour level represents 3σ above the average background surface brightness, with the remaining levels marking 25%, 50%, and 75% of the maximum above this level. Bottom left: same as top left but with 20 cm radio contours from Fig. 1 overlaid. The contours are at 1.5, 2.0, 2.5, 3.0, and 3.5 mJy/beam. Bottom right: Spitzer MIPS 24 μm image of the MCSNR J0512−6707 region with the X-ray contours from top right in white and [S ii]/Hα contours from top left in green. The cyan contours represent the CO emission from the MAGMA survey and delineate the location of the molecular cloud [WHO2011] A126. The lowest level corresponds to 1.2 K km s^-1 (the approximate sensitivity limit of the survey), increasing in steps of 1 K km s^-1. The image scale is the same as in all other panels.
