Notes. The second column lists the barium abundance in the logarithmic scale log N(H) = 12. Abundance errors induced by those of S/N, T_eff, and υ_mic are listed individually (in this order); whereas the total error is given in brackets. Third column lists the isotopic ratios in terms of s-process percentage. Its errors induced by those of the S/N, A(Ba), T_eff, υ_mic, and [Fe/H] are listed individually and in this order. The total error is given in brackets. Fourth column lists the microturbulence determined from Eq. (1), which is equivalent to $v_{m i c}^{B a}$ $v_{mic}^{Ba}$ .
