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.
