\caption{Log of the high-resolution VLT-UVES observations. Small
spectral gaps occur between 5757~\AA\ and 5833~\AA\ and between 8521~\AA\ and
8660~\AA\ due to the spatial gap between the two UVES CCDs. Since continuum
spectral intervals are hardly found in the spectrum, the signal-to-noise ratios
$S/N$ given in the rightmost column, are only indicative, and should be
interpreted more as lower limits than as fixed values.}\label{tab:observations}
