Notes. The values quoted by Stickland et al. (1996), Howarth et al. (1997), and Penny et al. (1999) were obtained by cross-correlation techniques applied to IUE spectra. The values of Mayer et al. (2008) were obtained through comparison of the He I λ 4922 line with rotationally broadened synthetic spectral lines.
