Fig. 6
NLTE abundances of HD 84937 (left panel) and HD 140283 (right panel) from lines of Fe I (circles) and Fe II (triangles) in the YBK18+YBK19 scenario as a function of observed equivalent width Wobs. The filled and open symbols correspond to the visible and UV lines, respectively. In each panel, the dotted line indicates the mean abundance derived from the Fe I visible lines.
