Abstract:
We report on high-resolution spectroscopy of four giant stars in the
Galactic old open clusters Berkeley 22 and Berkeley 66 obtained with
HIRES at the Keck telescope.
Description:
The observations were carried out on the night of 2004 November 30 at
the W. M. Keck Observatory under photometric conditions and a typical
seeing of 1.1".

Note on table3.dat: For Be 66-934, no abundance determination was possible
because the signal-to-noise ratio (S/N) in our spectrum was
too low to perform any equivalent width determination.
