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