Notes. All images corresponding to the same source are grouped together and separated by horizontal lines. (1) Multiple-image identification with N ≤ 50 come from (Coe et al. 2010). The same convention is used for the new multiple images identified by MUSE. Multiplicity or substructure within the same image is indicated by the extension “ext”. (2) Redshifts based on ref. vacuum wavelengths. (3) Main emission line.
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.
