Abstract:
Photospheric parameters and abundances are presented for a sample of
single-lined chromospherically active binaries from a differential LTE
analysis of high-resolution spectra. Abundances have been derived for
13 chemical species, including several key elements such as Li, Mg,
and Ca.
Description:
The spectra were acquired in January 2000 at the ESO 1.52-m telescope
(La Silla, Chile) with the fiber-fed, cross-dispersed echelle
spectrograph FEROS in the object+sky configuration. The atomic data
have been calibrated using a high S/N moonlight spectrum extracted
from the archive of the first FEROS commissioning period (fall 1998).

Note (1): A blank indicates that the EW was not reliably measurable for
one of the following reasons: the line was affected by telluric
features or cosmetic defaults (e.g., cosmic rays), the line was
significantly van der Walls broadened, or the Gaussian fit was
judged unsatisfactory.
