Example of a best fit for the X-shooter spectrum of CVSO 176 obtained with the fitter described in Sect. 2.5.1. The spectrum of the target is shown with a red line, the best fit photospheric template with a green line, the slab model with a cyan line, and the best-fit sum of the template and slab model with a blue line. The best fit is only shown up to 1000 nm, since the contribution from the disk emission can be significant at longer wavelengths.
