Notes. Values from the data in Table A.1. Numbers in brackets are the EW relative variabilities. Typical uncertainties are δ(|σ/⟨ EW ⟩|) ~ 0.03, 0.15, 0.16, 0.14 and 0.12 for the Hα, [O i]6300, He i5876 and Na iD2 and D1 lines, respectively. δ(σ/ ⟨ W10 ⟩ ) ~ 0.01. Propagated uncertainties ( ± ) are indicated for the non-variable objects. Values in parentheses indicate those lines shown both in absorption and emission. Only the values of the most frequent absorption/emission behaviour are considered in these cases to derive the mean values.
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.
