Optical/UV SED model adopted for this study (a) without absorption, for different values of kT_max (dash-dotted lines), keeping K_uvo constant at 2 × 10⁵, and for different values of K_uvo (dashed lines), keeping kT_max constant at 2.7 eV and (b) with absorption, for different values of E(B − V)_HG, with kT_max = 2.7 eV, K_uvo = 2 × 10⁵, and E(B − V)_MW = 0.05. The former plot shows possible degeneracy between parameters kT_max and K_uvo, while the latter shows effects of host galaxy dust extinction on the optical/UV SED model, almost negligible for E(B − V)_HG ≤ 0.01.
