Notes. For those cases when a four-Gaussian fit was feasible, the parameters of the weak “d” and “s” components that appear redshifted with respect to D and S, respectively, are also given. “N” is the number of spectra. (a) Radial velocities and velocity dispersions for these two dates have been taken from Welsh et al. (1998), since the observations were not available for direct measurements following the same method used in this work. (:) Noisy spectra.

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.
