Upper panels: ionization equilibrium for the targets 100932329 (UVES star) and 101565091 (Hydra star). Lower panels: equilibrium of the A(Fe)s and their EWs. Open and filled circles represent the abundances of Fe I (A(FeI)) and Fe II (A(FeII)), respectively. Red and black dashed lines represent the mean value of A(Fe) and standard deviation, respectively.
