Centre de Données astronomiques de Strasbourg (CDS) Hierarchical Progressive Survey (HiPS) color composite image of the region around the pulsar, retrieved from Aladin Sky Atlas. Red represents the soft X-ray (0.5–1.2 keV) data taken by Chandra ACIS, while green is the medium band (1.2–2.0 keV) of the same. The source seen in the image is most probably the X-ray counterpart of PSR J2238+5903. The point sources mentioned in Table 6 are shown with a white X with the corresponding MJDs and positional error ellipses. The green vector shows the direction of motion if the pulsar originated from the position we found using the OB-runaway proper motion.
