Fourth and fifth columns give HD 49933 abundances relative to the solar values from Asplund et al. (2005) (AGS) and from Grevesse & Sauval (1998) (GS), respectively. The sixth column gives abundances derived by Bruntt et al. (2008) relative to GS. The last column gives the abundances of the solar atmosphere from Asplund et al. (2005).
