Notes. Error bars are 2σ error bars unless noted otherwise. Note that the error bars for the 11 523 dataset are likely underestimated because of the tight constraint on b for this dataset (Sect. 3.2). The values in parentheses could be affected by systematic uncertainties on the b value or due to spurious features (see text). The O i column density in dataset 12 028 is an upper limit since it is determined using the undetected λ1355 line.
Column density calculated by the Cloudspec model (Sect. 4). The value in parentheses gives the correction when the emission component is accounted for (Sect. 4.2).
Estimated using S ii column density as a tracer (Sect. 6.2).
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.
