Example of a host-galaxy-dominated SED, with elements as in Fig. 14. Here, the SED is dominated by galaxy components (purple and green curves), including nebular emission lines (grey). The stellar mass and star formation rate are well constrained (numbers on the right), while the AGN luminosity has more than an order of magnitude uncertainty around a low value of 10⁴¹ erg s⁻¹. Here, model uncertainties (thin cap error bars) were only slightly increased without requiring an AGN component.
