Notes. For the benchmark stars the first row lists the literature values (references in Table 3), the second row the values derived in this work. Uncertainties are 1σ values from the line-to-line scatter. If only one line was fitted, no uncertainty is provided. (a)Phosphorus literature abundance from Aschenbrenner et al. (2025), (b)Nieva & Przybilla (2012), (c)Przybilla et al. (2013), (d)Aschenbrenner et al. (2025).
