Notes. The data adopted in this work are described in the text, and for kH, they are taken from Kreckel et al. (2010), for k3H from Forrey (2013a), and for ke based on Andersen et al. (1995) and Vejby-Christensen et al. (1996). The data adopted by LP68 are for kH based on Dalgarno & Browne (1967), for k3H based on a semi-empirical expression (their Eq. (11)), and for ke from Thomas & Athay (1961).
