X-ray count rates from the Swift (black crosses), XMM-Newton MOS1 (diamonds), and MOS2 (squares) observations discussed in Sect. 3.2. Colors indicate data from different XMM-Newton observations: revolution number 0814 = brown; 0818 = green; 0819 = blue; 0823 = red; 0827 = light blue; 0895 = yellow; 2272 = purple; 2275 = dark blue; 2283 = dark green; and 2292 = pink. Swift data have been converted into an XMM-Newton equivalent count rate using the WebPIMMS software package. From top: count rate in the soft (0.4−2.0 keV), medium (2.0−5.0 keV), hard (5.0−8.0 keV), and total (0.4−10.0 keV) bands versus phase. All data have been wrapped in phase so that more than one complete cycle is shown. The dotted vertical lines represent phases 0.0, 0.5, and 1.0.
