Notes. All temperature units in this table are main-beam, Tmb. Values in parentheses are the 1σ uncertainties. The total line flux is the sum of the individual components, and the total uncertainty is calculated by adding in quadrature the individual uncertainties. Systemic velocities are heliocentric, taken from NED, and used as the (optical convention) reference in Fig. 1.
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.
