Notes. Equivalent widths are grouped by redshift and spectroscopic mode (Grating = G, Prism = P); values are given separately for broad and narrow components where applicable. Line limits are given in narrow components unless otherwise specified.

(†)

These lines were fitted with narrow+broad components but are reported only as totals, since the prism resolution does not permit a reliable decomposition.

(‡)

Lines covered by fewer than 70% of the individual spectra were excluded from the stacked spectrum and therefore not fitted.

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.
