Notes. In italics, we display the results from the DETAIL/SURFACE analysis by Morel et al. (2006,2008). (a) Not corrected for centrifugal acceleration due to stellar rotation. (b) Solar helium abundance: n(He)/n(H) = 0.10. (c) Solar silicon abundance: $\hbox{$\log~n$ (Si)/$n$ (H)}= -4.49$. Interpolated values are listed.
