The catalog discussed here has been derived by choosing suitable input data (mostly from the literature), applying initial corrections to those data, and then subjecting them to a statistical analysis. Improvements in the published data include 1) correction to a common temperature scale, 2) correction of the output averages to a zero point which is presumably uniform, and 3) derivation of rms errors for those averages. The final version of the catalog is available from the Strasbourg Astronomical Data Center (CDS) and has entries for 941 stars. A sample of the catalog is given in Table 7.

$^{{\rm a}}$
This sample reproduces catalog entries, but differs from the catalog in format. For [Fe/H] and $\sigma$ , units are dex.
$^{{\rm b}}$
The numbers listed are HD numbers. In the catalog, prefixes designate other star catalogs, while "A'' and "B'' suffixes designate components of binaries (when required).
$^{{\rm c}}$
This is the number of degrees of freedom.
$^{{\rm d}}$
The numbers correspond to the following literature sources: 166, Branch & Bell (1971); 565, Balachandran (1990); 624, Edvardsson et al. (1993); 2001, Raff (1976); 2003, Nissen (1981); 2004, Clegg et al. (1981); 2055, Fuhrmann (1998); 2072, Chen et al. (2000). In the catalog, a complete list of numbers and references appears in a supplementary list.
