Notes. (a) Optically thick emission line and self-absorbed. τmain is the opacity of the main component. The optical depth of the most optically thin component is τmain multiplied by 0.2 (in the case of H13CN, HCN and N2H+), 0.01 (DCN) or 0.11 (N2D+).

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.
