Notes. For each abundance, the (asymmetric) errors refer to the 1-σ errors derived from the 
distribution (first number), and to the approximate total error budget estimated from additionally accounting for typical uncertainties in the stellar parameters (second number, separated by |). The table also provides the number of lines used for the χ2 analysis of a specific object/atomic species. For comparison, the maximum number of lines (for all ions) considered in our spectrum synthesis is 12 for carbon, 17 for nitrogen, and 10 for oxygen. The oxygen abundances for (at least) the cooler dwarfs (#1 to #5) should be considered with caution, since they might be affected by an imperfect model atom (see text).
