Notes. For each chemical species, we list: the number of individual MP SAGA stars (from Table 2) with abundance measurements, N⋆, the mean and maximum combined standard deviation of NLTE corrections across all possible line subsets, σ¯c$\[\bar{\sigma}_{c}\]$ and σc,max, the fraction of stars with σc > 0.1 dex, the fraction of stars with σc > |ΔNLTE|/4 and the union of the two (see text for details).
