Notes.The average 1D TOP-star abundances were derived from the co-added TOP-star spectrum while the abundances for the other groups are computed as the mean abundance of the abundances derived for the individual stars within each group. The 3D abundances are derived by applying the corrections given in Table 7. The uncertainties on the abundances for the TOP-group correspond to the standard deviation. For the other groups, they correspond to the standard error of the mean (see text).
