Phase-folded X-ray light curves of J071126 in both observations, for the EPIC-MOS1, MOS2, and pn instruments. The light curves have been binned into 100 bins per cycle, and two phases are plotted for clarity. The energy ranges are 0.2–12 keV for the EPIC-MOS instruments and 0.2–15 keV for EPIC-pn, and count rates have been corrected for the enclosed count fraction of the source extraction regions. Dotted vertical lines indicate the beginning and end of the bright phase, clearly showing the longitudinal shift.
