Notes. Barycentric Julian dates are given in barycentric dynamical time (BJD_TDB; Eastman et al. 2010). The entire data set is available in a machine-readable table at the Strasbourg astronomical Data Center (CDS).

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.
