Abstract:
In this paper, an updated catalog containing averaged values of [Fe/H]
is presented for FGK stars on and near the main sequence. The input
data for the catalog are values of [Fe/H] derived from weak and
moderately strong lines and published before 2005 July 1. Those data
are corrected to a uniform temperature scale, and a statistical
analysis is then applied to a subset of the data that did not
contribute to a previous version of the catalog. In this way, it is
found that an accurate zero point for the catalog can be established
with an rms error of 0.005dex. After corrections are applied to a
number of the newly added data, it is shown that those corrections
help to produce satisfactory zero-point coherence among the catalog
entries. Standard errors that are derived for the catalog data are
shown to be accurate. It is also shown that those standard errors are
based on pervasive scatter in the input data, as is expected if those
data are affected by genuine random effects. Samples of the
metallicity catalog and an accompanying temperature catalog are
displayed and discussed. To make possible an effective extension of
the catalog to stars without catalog entries, a database containing
photometric metallicities derived by Nordstroem et al. (2004, Cat.
V/117) is considered. Standard errors for those metallicities are
derived, and zero-point corrections required to put those data on the
catalog zero point are presented.
Description:
table 8 contains values of θ [=5040/T(eff)] for 1344 F-K stars
that are on or near the main sequence. Values of Cousins R-I are also
given for most stars.
Table 9 contains mean values of [Fe/H] (with rms errors) for 1331 F-K
stars that are on or near the main sequence. Literature references are
given for the contributing values of [Fe/H].
