Left: intensity-scaled broadband XMM-Newton X-ray image of DEM L299. The image shows an area of in the energy range of 0.3–8.0 keV and has been smoothed by a Gaussian with a kernel radius of four pixels, after being adaptively smoothed. Right: three-colour image created out of XMM-Newton data. Red: 0.3–0.8 keV, green: 0.8–1.5 keV, blue: 1.5–4.5 keV. To create the image, the same area, the same kernel radius, and the same scale units were used as for the broadband image. The scales are in counts/s/deg².
