Notes. The date quoted in Col. 3 and the duration given in Col. 4 correspond respectively to the middle and the total duration of the usable exposure of the EPIC-pn instrument (i.e. after discarding intervals of soft proton background flares). The EPIC modes are labelled as S for small window mode and T for timing mode. The last column quotes the orbital phase of the observation using binary orbital solution number 5 of Nemravová et al. (2012), with P = 203.523 d and T0 = 2 452 081.89 corresponding to the epoch of minimum RV of the Be star.
