Normalised FUSE, IUE and X-shooter spectra (blue line) compared to the synthetic composite spectra from our best-fit model (red line). The UV FUSE and IUE data are normalised by dividing the absolute flux by the sum of the continuum of the primary and the secondary model. The ground-based X-shooter spectra have not been corrected for H₂O and O₂ molecular absorption bands in the near IR.
