Notes. To save space, the initial two digits (24) have been omitted from the timings. Offsets compared with the ephemeris of S+15 are given in seconds. The cycle numbers are given according to the ephemeris in S+15. For the last cycle of Obs2, we have used the EPIC-MOS2 data because of data interruptions in EPIC-pn. Weighted averages for eclipse offsets and durations are given in the final row.
