^(a) ‘Th’ and ‘Med’ stand for the thick and medium optical blocking filters, respectively.

^(b) Total duration of the observation.

^(c) LIVETIME is the livetime keyword value corrected for periods of dead time and high background (wherever located).

^(d) Background corrected net source counts have been estimated in 0.3-10.0 keV energy range.

^(e) Offset between HD 93250 position at EPIC instruments and the telescope pointing.

^(f) The observing modes of observations are (i) PFW: Prime Full Window, (ii) PLW: Prime Large Window (covering full field of view), (ii) PPW2: Prime Partial Window2 (small central window), (iii) PPW3: Prime Partial Window3 (large central window).
