Table 7: EW-measurements for HD 92024 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 EWs for three different temperatures. The last columns give EWs for the two composite spectra, combined from all 103, and from 10 similar spectra.
