Notes. Table columns: (1) Wavelength of C IV zero-point velocity; (2) median velocity uncertainty (the individual velocity errors δv are used in Sect. 5 to carry out the bootstrap analysis on σ⊥ and in Sect. 6 to produce v = 0 mock catalogs. These are listed in Table A.1 and their distributions displayed in Fig. B.1); (3) instrumental profile width at λ1548 (σinst is used to compute σ∥ in Sect. 5. σinst was obtained at each system’s wavelength by interpolating the values measured by Mentz et al. (2016) using sky lines); (4) spurious σ⊥ (Sect. 5 and Appendix D); (5) slope of exponential fit to W0-completeness (Sect. 3.4).
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.
