The atmospheric parameters ($T_{\\rm eff} = 7600$ K, $\\log g = 4.2$, $\\xi = 3.1$ km s$^{-1}$ and $ {\\rm [Fe/H]} = -0.71$ dex), the radial and rotation velocities, and elemental abundances were obtained by analysing line strengths and fitting line profiles, which were calculated with a 1D LTE model atmosphere.
