Notes. For each molecule, the total number of detected lines and the diameter of the maximum angular size (in mas) is listed, if detected. The hypercomponents for AlO, AlOH, and NS are counted separately, albeit often they can not be spectrally resolved.

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.
