Notes. Numbers in parentheses represent the derived uncertainty (1σ) of the parameter in units of the last digit. This molecular species is only visible in the Yebes 40 m telescope data. ( * )The line is partially blended with another feature but a fit to the frequency can be obtained by fixing the expanding velocity to 14.5 km s−1. However, the integrated line intensity is very uncertain and it is not used for the rotational diagrams.
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.
