\caption{Log of the UVES observations. The $S/N$ ratio per pixel is 
given for 
three representative wavelengths.  (Due to the large number of pixels
in each resolution element, the $S/N$ ratios of the table need to be
multiplied by a factor of 1.3 in order to compare them to the values
available in the literature).}\label{tab-Obs}
