Notes. 1. Observations already published by Jordan et al. (2005). 2. The field is estimated from absorption lines only. 3. Many spectral lines are in emssion, and the field is estimated from absorption lines only. 4. Non-magnetic B9V star observed for comparison. Teff and log g from: 5.Traulsen et al. (2005). 6. Lisker et al. (2005). 7. Napiwotzki (1999). 8. Mendez et al. (1992). 9. Mendez et al. (1988). 10. Pottasch et al. (2011).
