Summary of parameters used in Fig. 4.

Model	G₀	F_UV [photons/cm²/s]	E_hν [eV]	A_V [mag]	Line style
DISM	1	3 × 10⁷	8	0.1	Dotted
edge	1	1.2 × 10⁷	10	0.5	Short dash
edge	1	7 × 10⁶	12	0.5	Long dash
HII	10⁴	7 × 10¹⁰	30	0.1	Solid

Notes. Assuming E_g = 0.1 eV, E_loss = 6.4 eV, and k₀ = 10¹⁶ s⁻¹. The various models are for: the diffuse ISM (DISM), cloud edges (edge) and an extreme PDR/H II region (HII).
