Notes. The optical/UV eclipse times (1st column), the corresponding time-lags (2nd column) with respect to the best-fit parabola describing the X-ray ephemeris showed in Eq. (5), the time-lags after removal of the sinusoidal modulations (3rd and 4th column, respectively). The errors are at the 68% c.l.
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.
