Notes. We report as the confidence result the median value of the posterior probability distribution, while the upper and lower uncertainties correspond to the 16th and 84th percentile respectively. *this source is strongly lensed.

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.
