Notes.From left to right, the columns are (1) source name; (2) the integrated intensity ratios ICN/IHCN; (3) the integrated intensity ratios ICN/IHNC; (4) the integrated intensity ratios IHCN/IHNC; (5) the integrated intensity ratios IHCO+/IHCN. (6) the infrared luminosity of the galaxy; (7) the type of the galaxy where L, A, and S represent a luminous infrared galaxy, an active galactic nucleus, and a starburst galaxy. The data shown here come from Costagliola et al. (2011).

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.
