Notes. A ‘<’ symbol corresponds to no detection. The log of the column densities of H2 and H I taken from the literature or derived from CH (N(H2)c) and the 5780 Å DIB (N(H I)c) are also shown, along with the fractional H2 content or its value derived from CH and the 5780 Å DIB, (fH2c). HWV refers to sightlines that had high water vapour affecting the 1318 nm DIB measurements and EmL observations affected by emission lines in the DIB.

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.
