Notes. The durations indicated in the third column correspond to the effective exposure time of the EPIC-MOS camera (i.e. after removing the time interval affected by a flare in the first and third observation). The Julian day given in Col. 4 is evaluated at mid-exposure. The last four columns yield the orbital phases respectively for HD 168112 (Putkuri et al. 2023; Blomme et al. 2024), the eclipsing inner binary of HD 167971 (Ibanoglu et al. 2013) and the orbit of the outer component of HD 167971 (Le Bouquin et al. 2017).
