Field of view (15′ radius) of both XMM-Newton exposures (all EPIC cameras combined; March 2023 on top, October 2023 at the bottom). The yellow arcs mark the limit of the stray light contamination, the blue circles correspond to the source extraction regions (30″ radius), and the green circles are the background extraction regions (their size is limited by the “small window” mode: the smaller ones are for MOS cameras, the larger one for the pn camera).
