Notes. The 1σ uncertainties in the 3D non-LTE models take into account the uncertainties in the adopted surface gravities and metallicities, and uncertainties in placing the continuum, given in Table 1, as well as the formal fitting error. The uncertainties in the continuum placement dominate, except for H α in HD 103095, where the uncertainty in dominates. The last three columns show the differences between the models and the reference values adopted from the literature (Col. 2, also Table 1), with the uncertainties combined in quadrature (see Fig. 10 for an illustration of these differences).
