Notes. The values quoted by Conti & Ebbets (1977) were obtained by visual comparison with standards and the values quoted by Levato & Morrell (1983) were obtained by visual comparison with the standards given by Slettebak et al. (1975). The values of Sana et al. (2006) were estimated through a comparison of the measured Full Widths at Half Maximum (FWHMs) of the various lines with those measured, for a range of v sin irot, on model spectra of equivalent effective temperature and gravity computed using the codes TLUSTY and SYNSPEC.
