Examples of the best fit models (CIGALE SED fitting code). The left-hand side spectrum is a star-forming galaxy, while the spectrum shown on the right-hand side is ULIRG. Observed fluxes are plotted with open blue squares. Filled red circles correspond to the model fluxes. The final model is plotted as a solid black line. The remaining three lines correspond to the stellar, dust, and AGN components. The relative residual fluxes are plotted at the bottom panel of each spectrum.
