Table 2: Solar europium abundances from the adopted observed spectra. Column (1) indicates the solar spectrum used: KF: Kurucz flux, NF: Neckel flux, NI: Neckel intensity, DI: Delbouille intensity. Column (2) is the wavelength of the observed lines. Column (3) is the Equivalent Width. Columns (4) and (5) are Eu abundance from the \ensuremath {{\rm CO}^5{\rm BOLD}} models and the corresponding uncertainty due to the error of the Equivalent Width. Columns (6)-(9) are the results from the 1D chemical analysis by adopting two solar models (HM: Holweger & Müller (1974). FC: ATLAS9 solar model by Fiorella Castelli). Finally, Cols. (10) and (11) are the 3D corrections.
