Notes. Parameters related to NH3, N(H2), and S870μm are selected from Wienen et al. (2012). Distances are the kinematic distances presented by Wienen et al. (2015). Last column: HII = HII region, IRDC = infrared dark cloud, EGO = extended green object.

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.
