Notes. Column descriptions: λ: wavelength. E_low: lower level energy. “Waals”: parameters used to calculate line broadening due to collisions with neutral hydrogen. Integer component: broadening cross-section at a velocity of 10⁴ m s^-1 in atomic units. Fractional component: velocity parameter (see Barklem et al. 2000). If zero, the Unsöld approximation was used. “Ref”: reference code for the gf-values (see below). The remaining columns are headed by a label for each group defined in the text and the number of stars in parantheses. The columns give the minimum and maximum standard deviations of the average line abundances and the minimum and maximum number of abundances averaged for each line for each group. 5414.07 Å was not used in μ Cas and 5991.38 Å not in HD 49933. The column marks the lines used for ϵ Eri; of these, only 4993.36 Å and 6456.38 Å were used in 61 Cyg A and Gmb 1830; only 4993.36 Å and 5425.26 Å in 61 Cyg B.
