Details of observed WD spectrum compared with three models with different temperatures (Teff = 105 000 ± 5000 K) representing the error range in determination of Teff. Left: O IV multiplet gets weaker with increasing Teff, as well as lines from Fe VI and Ni VI, while Fe VII lines get stronger. Right: same behavior of oxygen and iron lines in another wavelength range.
