Notes. All data are from Emprechtinger et al. (2009). (a)This is computedas the ratio of the canonical CO abundance to the observed one, the former being obtained from H2 column density via Xmol(C18O)∕Xmol(H2) = 1.7 × 10−7 (Frerking et al. 1982).

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.
