EPIC-pn light curves (from top to bottom: 0.15–0.5 keV, 0.5–1 keV, 1–2 keV, and 2–8 keV) extracted from the source (black) and background (red) regions during the three XMM-Newton observations performed in 2016 (0761630101, 0761630201, and 0761630301). The background count rates (and error bars) are rescaled by a factor 10 to account for the different sizes of the source and background regions.
