Relevant parts of the co-added UVES spectrum compared with our best-fit model (in red; 175 000 K and log g = 7.7; other parameters are listed in Table 2). To reduce the noise the observation was convolved with a Gaussian (full width at half maximum = 0.2 Å). Photospheric lines are marked in red, artefacts in grey.
