A comparison of the disentangled line spectrum of the HD 31894 secondary with a synthetic spectrum interpolated from the Bstar grid for T_eff = 17 810 K, log g = 4.52 [cgs] and v sin i = 26.9 km s^-1 in three spectral segments containing stronger stellar lines. In all cases, dots denote the observed spectrum, while the synthetic spectra, shifted for the systemic velocity of −2 km s^-1, are shown as thin lines. A relative luminosity of the secondary of L₂ = 0.191 was adopted for the comparison.
