Best SED-fitting obtained with FADO for the MR and MP regions, defined in Fig. E.5. The orange and blue lines represent the MR and MP observed spectra, respectively. The black line show the best-fitting model, and the gray and green curves show separately the stellar and nebular continuum contribution, respectively. It is clear that the MP region (bottom) requires a more significant contribution of nebular continuum than the MR (top) region.
