Three-colour image consisting of a red image for the soft band XMM-Newton image (0.3−0.9 keV, Sasaki et al. 2004), a green image for Mg (1.25−1.45 keV) – continuum, and a blue image for Si (1.7−2.1 keV) – continuum. The Mg and Si images were created from the Chandra data. The green dashed box indicates the field of view of the Chandra ACIS-I. The yellow cross indicates the present position of the AXP 1E 2259+586.
