Notes. The columns are (from left to right): the source designation, transition frequency, LSR velocity, FWHM of the line, peak TB, the corresponding line ratio Ri, i = 1, 2 where R1 = T3.264 GHz∕T3.349 GHz and R2 = T3.335 GHz∕T3.349 GHz and the gas density, and temperature derived from the non-LTE radiative-transfer modelling.
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.
