Chandra image in the 0.3–5 keV energy band after a Gaussian smoothing. The positions of the pulsar, the nebulae, and the serendipitous Galaxy cluster are labeled. The image axes are aligned in right ascension and declination with north to the top and east to the left. The angle θ used for the MRHT is defined such that zero is at 90° toward east with respect to the north Celestial Meridian and is measured in the counter-clockwise direction from 0° to 180°.
