Notes. From left to right: EMPEROR with reddemcee, EMPEROR with dynesty, and juliet with dynesty. From top to bottom: white noise model (0K) and single Keplerian (1K), each tab contains descending the total run time in seconds, eff (the sampling efficiency), enits (effective samples per second), the Bayesian evidence estimate, its estimated uncertainty, and the χ2 test between internal and empirical evidence uncertainties.

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.
