Notes.

^(a)

Julian day at mid-exposure.

^(b)

Orbital phase of the binary computed from the new orbital solution given in the bottom section of Table 3.

^(c)

The position angle is zero when the primary star is in front of the secondary.

^(d)

Distance between the stars normalized by the semimajor axis computed from the new orbital solution.

^(e)

Effective exposure time of the EPIC/pn camera after discarding soft-proton flares.

^(f)

Net count rates for the three EPIC instruments over the 0.2−10 keV energy band.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
