Notes. The last two columns indicate the combined total expected uncertainty and the observed dispersion from Table 2, respectively. Column ϵ(S/N) indicates the minimum and maximum abundance variation observed from Table 2 (error of the mean) or, when only one or two lines were measured, expected according to the EW error induced from the spectral S/N or as returned from the fitting procedure in the case of spectrum synthesis.
