Notes. “–” Indicates non-detection at a 3σ peak brightness in either tracer. For NH2D detection with no NH3 we have used an excitation temperature of 16 K (± 5 K) for computing the column density. Ratios have been quoted only when the error estimate is below 50%.
Core names from the original NH2D data (see Table 4) have been assigned to the cores in the smoothed NH2D data.
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.
