Notes. From left to right the columns are: source name, coordinate, dust temperature, total H volume density, and H2 column density. “*” indicates that the column density of H2 is obtained from Planck. “†” indicates the two sources where the column density may be underestimated, and they are not involved in the analysis and discussion in the main text.
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.
