Smoothed false-colour (top) and source detection (bottom) images of the two XMM-Newton observations covering the position of J0221. The red band covers the energies from 0.2−1.0 keV, green from 1.0−2.0 keV, and blue from 2.0−12.0 keV. The position of the target and of other sources detected in the field-of-view are marked by white and light blue circles, respectively.
