3 arcmin × 3 arcmin Chandra X-ray image of the pulsar vicinity in 0.5–10 keV range smoothed with a 25 pixel Gaussian kernel. The ‘+’ symbol shows the pulsar position. The ‘jet’ and ‘counter-jet’ are marked. The 30 arcsec × 30 arcsec image part, enclosed by the cyan dashed box and smoothed with a 3 pixel Gaussian kernel, is enlarged in the inset. The possible PWN torus and the base part of the ‘jet’ are marked.
