Notes. In addition to the median of the posterior of the one eccentric planet + GP-SHO models, we give the 16th and 84th percentile confidence interval. The blocks are sorted into the directly inferred orbital elements, derived elements, GP hyperparameters, RV-jitter and -offset.

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.
