Notes. τ is the e-folding time of the main stellar population model in Myr, age is defined as the age of the main stellar population in the galaxy in Myr, and burst age is the age of the late burst in Myr. Here, β and γ are the parameters used to define the law for the spatial behaviour of density of the torus density. The functional form of the latter is ρ(r, θ)∝r^βe^{−γ|cos θ|}, where r and θ are the radial distance and the polar distance, respectively. Θ is the opening angle and Ψ the viewing angle of the torus. Type 2 AGNs have Ψ ≤ 30° (edge-on) and Type 1 AGN have Ψ ≥ 70° (face-on). 40° ≤Ψ ≤ 60° corresponds to intermediate-type AGNs. The AGN fraction is measured as the AGN emission relative to IR luminosity (1−1000 μm).
