Fig. A.3
Left panels: behaviour of the abundance of Fe I lines as function of the excitation potential χ for the Li-rich stars, red circles for #25664 (upper left panel) and blue circles for #126107 (lower left panel). Right panels: spectral region around a Fe I line in #25664 (upper right panel, red line) and #126107 (lower right panel, blue line), both compared with stars in Omega Centauri with similar metallicity and atmospheric parameters as shown in Fig. 1.
