NLTE corrections for the Eu II λ 4129 Å line (left panel) and λ 6645 Å line (right panel) are plotted against the metallicity [Fe/H] of the model atmospheres. The red line represents the NLTE correction of red giant with parameters of T_eff=4500 K/log 𝑔=1.5 dex, the blue line represents the NLTE correction of subgiant with parameters of T_eff=5500 K/log 𝑔=3.5 dex, and the black line represents the NLTE correction of main-sequence star with parameters of T_eff=6000 K/log 𝑔=4.0 dex. The NLTE calculations were performed assuming [Eu/Fe] = 0.
