Abstract:
We present Mn, Co and Eu abundances for a sample of 20 disk F and
G dwarfs and subgiants with metallicities between -0.8 and +0.3. We
investigate the influence of hyperfine structure (HFS) on the
derived abundances of Mn and Co by using HFS data from different
sources in the literature, as well as calculated HFS from
interaction factors A and B.
Description:
The files table2.dat and table3.dat contain the [Mn/H] and [Co/H]
abundance ratios, respectively, for all measured lines, sample stars
and sources of hyperfine splitting structure. Some lines have not been
effectively used in some stars; these have abundance ratios equal to
+9.99 in the files.
