Notes. The second column gives the variation in the abundance caused by the variation in Teff. The other columns refer, respectively, to the variations due to log g, ξ,  [Fe/H]  and Wλ. The seventh column gives the compounded rms uncertainty of the second to sixth columns. The last column gives the observed abundance dispersion for those elements whose abundances were derived using more than three lines.
