Notes. All EWs are in Å. EW errors are obtained from bootstrap resampling of the spectrum (see Sect. 2.3) and account for the uncertainty in continuum fitting. If a line is not covered by the spectral range of MUSE, the EW is shown by a long dash. If a line is covered but the continuum level around the considered line is below the error level, the ΔEW is shown by a long dash. In these cases, the EW is computed assuming that the continuum level equals the noise level, and the EW presented should be considered as a lower limit.

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.
