EPIC spectrum of A1213 extracted from the white circle shown in Fig. 11. The circle has a radius of 5′. Black points are MOS1, red points MOS2, and green points pn detector data. The lines are the best-fit sky background and source models for the three EPIC detectors. The data around 1.5 keV and 7 keV are excluded from the analysis to avoid strong instrumental line emissions (see Ghirardini et al. 2019). The bottom panel shows the data divided by the folded model.
