Notes. Column 2: solar abundances scaled to the metallicity of 10 Leo. Column 3: abundances for 10 Leo derived in this paper by spectral synthesis. Column 4: abundances for Arcturus derived in this paper. Column 5: differences between 10 Leo and Arcturus abundances. (a)Only neutral lines were used for all elements except for Sr, for which only ionised lines were used. (b)The solar-scaled abundances are based on the element abundances in the solar photosphere derived by Grevesse & Sauval (1998).
