Overview of the AGN model parameters and how they configure the spectrum, shown here in L_λ with arbitrary units. The power law (blue) is normalised at 5100 Å, where it has a power law slope of β. The power law bends over at λ_bend towards the UV, where it has slope β_UV. The width of this transition is set by W_bend. Emission lines with FWHM W_lines and an FeII template are added and can be further scaled by A_lines and A_FeII, respectively. The torus component (dark yellow) is normalised by the ratio of 12 μm and 5100 ÅλL_λ luminosities, f_cov (see Eq. (4)). It consists of the sum of two log-quadratic curves, with width W_cool and W_hot and location λ_cool and λ_hot. The peak-to-peak λL_λ ratio is set by f_hot (see Eq. (3)). The depth of the Si feature, in emission if positive or in absorption if negative (here: −1), is set by Si. The flexibility of these 15 parameters is restricted in Section 2.2.
