Fig. 1.
Ni IIλ1741 absorption profile for the five systems considered in this study. The redshift of the strongest narrow absorption feature is indicated at the lower left corner of each panel and corresponds to vhelio = 0 km s−1. All features appearing in these profiles are from the Ni IIλ1741 transition except that shaded in the middle panel.
