Table 2.

Parameters to model the emissivity ϵ(ν, z).

Parameter	Fiducial value	Parameter	Fiducial value
${log}_{10} ϵ_{1500}^{z = 0}$ $\log_{10}\epsilon_{1500}^{z=0}$	25.63	γ₁₅₀₀	2.06
$α_{1500}^{z = 0}$ $\alpha_{1500}^{z=0}$	−0.08	C₁₅₀₀	1.85
$α_{1100}^{z = 0}$ $\alpha_{1100}^{z=0}$	−3.71	C₁₁₀₀	0.50
$α_{900}^{z = 0}$ $\alpha_{900}^{z=0}$	−1.5	EW^z = 0.3	−6.17 Å
EW^z = 1	88.02 Å	EW^z = 2	176.7 Å
${log}_{10} f_{LyC}^{z = 1}$ $\log_{10}f_{\mathrm{LyC}}^{z=1}$	−0.53	${log}_{10} f_{LyC}^{z = 2}$ $\log_{10}f_{\mathrm{LyC}}^{z=2}$	−0.84

$b_{1500}^{z = 0}$ $b_{1500}^{z=0}$	0.32	γ_ν	−0.86
${log}_{10} {[ϵ b]}_{1500}^{z = 0}$ $\log_{10}[\epsilon b]_{1500}^{z=0}$	25.62	γ_z	0.79

Notes. The parameter ${log}_{10} {[ϵ b]}_{1500}^{z = 0}$ $\log_{10}[\epsilon b]_{1500}^{z=0}$ collects the degeneracy between $ϵ_{1500}^{z = 0}$ $\epsilon_{1500}^{z=0}$ and $b_{1500}^{z = 0}$ $b_{1500}^{z=0}$ .
