Notes. From left to right, the columns give the star name, the abundances from both neutral and ionized lines, their uncertainties, and the number of spectra used. These are the weighted mean values and their standard errors computed from the individual measurements listed in Table 8. The standard deviation calculated using all individual abundances from both neutral and ionized lines is also shown. The complete table is available at the CDS.
