Notes.

(a)

Column density in cm−2. Upper limits correspond to 3σ values.

(b)

Relative abundance to H2 assuming a total column density of molecular hydrogen of 1022 cm−2 (Cernicharo & Guélin 1987).

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.
