RGB-composite (top left) and individual narrow-band X-ray images covering the 0.44–1.1 keV band. The red, green, and cyan (instead of blue, for better visibility) images correspond to the 0.44–0.62, 0.62–0.8, and 0.8–1.1 keV bands, respectively. These bands encompass the three brightest X-ray emission lines in the spectrum of S147: O VII, O VIII, and Ne IX.
