The second column provides the number of points in the dataset. The HJDs are given as HJD-2 400 000. Column four quotes the times of primary minimum t0 along with their estimated uncertainties. Columns five and six yield the epoch (i.e. the binary cycle) since the first t0 and the 
residual evaluated with respect to the quadratic ephemerides.
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.
Initial download of the metrics may take a while.
