Notes. Spectroscopic line parameters were obtained using MADEX by fitting all the rotational lines reported by Kisiel et al. (2009). Parentheses indicate the uncertainty obtained by the Gaussian fitting programme. (†)Owing to the weakness of these lines, we fixed vFWHM to 5.0 km s−1 in order to fit a Gaussian profile. We assume an uncertainty of 15% for this value. (††)These lines are below a 3σ level. We did not include them in the analysis of the rotational diagrams.
