Notes. Adopted solar parameters (Cox 2000): Teff = 5 777 K, log g =4.44, and ξ = 1.38 km s−1. (a) The uncertainty in the mean. For C, both spectral lines yielded the same abundance; for K and Y, the abundance was derived from a single spectral line; and for Co, all the spectral lines yielded the same abundance, except for one that differed by 0.01 dex. (b) The quadratic sum of the uncertainty in the mean and the uncertainties due to Teff , log g, and ξ. (c) Corrected for NLTE effects, see text.
