Notes. The adopted parameters are T_eff = 7700 K, log g = 4.2 (Ryabchikova et al. 1997). In the first column we present the observed wavelength followed by the central line depth and the name of the element. Columns 4–8 list laboratory wavelength, oscillator strength, excitation potentials for the lower and upper level of the transition and the source for the atomic data. In the last column we make notes referring to the presence of blends, Zeeman splitting, or spectral artifacts. The radial velocity shift between the observed wavelength positions of the spectral lines and their laboratory wavelengths is 44 km s^-1.
