Upper panel: curve of growth for both line lists for the reference star computed for the temperature (Θ = 5040/T_eff) of this work. Circles represent the reduced EW of the line list of this work and crosses the line list of SO08. Lower panel: the Fe i abundances of the reference star versus the excitation potential. The dashed line shows the positive slope that corresponds to the line list of SO08. The solid line corresponds to the line list of this work and the slope is obviously zero.
