Notes. X(Y) corresponds to X × 10Y. (a) x corresponds to the velocity range from − 110 to − 10 km s−1. (b) Measured brightness temperature in the Mopra spectrum, or upper limit of 3σ. (c) Range of densities consistent with the detected Mopra emission, or upper limit to the densities. The values in brackets give the high-density solution, when it exists.
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.
