Notes. We report redshift, i′ and Ks observed magnitudes, stellar mass, star-formation rate (as measured from SED fitting), β slope, and type (N: narrow He II emitters; B: broad He II emitters; P: probable He II emitters; A: AGN). We also report the average values for each group. Objects for which the β slope is marked with an asterisk have barely detected continua, and they have not been used to compute the average value of the narrow emitters.

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.
