 \caption{{\it EW}-measurements for \hd\ FEROS spectra and in model lines for 
  different 
  temperatures and abundances. The second column lists helium abundance for the 
  helium lines (using $\log g=3.8$) and metal abundance for selected metal
  lines ($\log g=4.0$), while Cols.~3--5 give corresponding model {\it EW}s for three 
  different temperatures.  The last columns give {\it EW}s for the two composite
  spectra, combined from all 103, and from 10 similar  spectra.
