Notes.From left to right, the columns are (1) source name; (2) integrated intensity of CN; (3) integrated intensity of HCN; (4) integrated intensity of HNC; (5) the integrated intensity ratios ICN/IHCN; (6) the integrated intensity ratios ICN/IHNC; (7) the integrated intensity ratios IHCN/IHNC; (8) the evolutionary stage of the source; (9) N signifies those sources that are not coincident with 20 cm continuum emission, and Y indicates sources that coincide with the 20 cm continuum emission.
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.
