Notes. In all cases, a background temperature of 2.7 K was used for each source. Tb is taken as the 3σ rms noise level at the location of the target line. Furthermore, all observations were taken with the IRAM 30 m telescope and it was assumed that the source fills the beam except in the case of SVS13A where a source size of 0.″3 was used. For additional information on each of the sources as well as a reference to the original citations where the physical conditions were measured, see Margulès et al. (2020a).
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.
