Notes. For each parameter, N_sample values are simulated in the values range. U_S refers to the ionization parameter at the Strömgren radius (see Feltre et al. 2016), Z to the metallicity, ξ_d to the dust-to-metal mass ratio, n_H to the cloud gas density, and α to the power-law index at UV and optical wavelengths of the AGN continuum (S_ν ∝ ν^α for 0.001 ≤ λ/μm ≤ 0.25). For the shock models, v_shock refers to the shock velocity, n_{H, pre − shock} to the pre-shock density, and B_transv to the transverse magnetic field; the investigated metallicity parameter space is the same as in the SF models.
