Notes. Spectroscopic data from JPL catalogue (https://spec.jpl.nasa.gov/). Parentheses indicate the uncertainty obtained by the Gaussian fitting programme. (†)Owing to the weakness of these lines, we fixed vFWHM to 7.0 km s−1 in order to fit a Gaussian profile. We assume an uncertainty of 15% for this value.

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.
