“Anatomy” of diffuse X-ray emission inside W50. The image shows a composite map of the X-ray surface brightness in 0.5−1,1−2, and 2−4 keV energy bands (similar to Fig. 3) after masking bright foreground and background point sources, and the central source SS 433. Overlaid in white are markers of the distance from the central source (assuming d_{SS 433}=5 kpc) and angle with respect to its orbital plane axis, coinciding with the precession axis of its narrow relativistic jets. The box regions, numbered from 1 to 6, are used for spectrum extraction and represent fiducial spectral components composing the image.
