X-shooter spectrum from the UVB and VIS arms with a best-fit model. The normalised flux is shown with solid black lines and the best-fit model is shown with dashed red lines. The parts of the spectra that were not considered in the fit are marked with a dashed black line and include diffuse interstellar bands due to the high reddening. The panels have different flux ranges. The strongest lines of hydrogen, magnesium, calcium, and iron are also marked. The Paschen lines are marked in the infrared, and some of them blend with Ca II lines.
