Table 6: Chemical composition of $\omega$ Ori compared to the mean chemical composition of B stars, as derived by Gies & Lambert (1992) and of local B stars, as derived by Gummersbach et al. (1998). The logarithmic abundances $\log$ ( $\epsilon _N/\epsilon _{\odot }$ ) are given relatively to the solar values compiled by Grevesse & Sauval (1998).
