Table 4.

Kendall τ correlation coefficients and the p-values between the radio spectral index ( $α_{6 GHz}^{3 GHz}$ $\alpha^{\mathrm{3\,GHz}}_{\mathrm{6\,GHz}}$ ) versus $f_{esc}^{LyC}$ $f_{\mathrm{esc}}^{\mathrm{LyC}}$ and different physical properties of LzLCS sample.

	$α_{6 GHz}^{3 GHz}$ $\alpha^{\mathrm{3\,GHz}}_{\mathrm{6\,GHz}}$
	τ	p_val

$f_{esc}^{LyC}$ $f_{\mathrm{esc}}^{\mathrm{LyC}}$ (UV-fit) ^( * )	+0.395 (0.285)	1.220 × 10⁻² (5.723 × 10⁻²)
$f_{esc}^{LyC}$ $f_{\mathrm{esc}}^{\mathrm{LyC}}$ (Hβ) ^( * )	+0.381 (0.261)	1.57 × 10⁻² (8.132 × 10⁻²)
β₁₅₅₀	−0.419	7.876 × 10⁻³
log₁₀O₃₂	+0.448	4.532 × 10⁻³
log₁₀Σ_SFR(Hβ)	+0.286	7.001 × 10⁻²
log₁₀M_*/M_⊙	−0.410	9.406 × 10⁻³

Notes. ^( * )Here, we take into account the upper limits on $f_{esc}^{LyC}$ $f_{\mathrm{esc}}^{\mathrm{LyC}}$ (following Akritas & Siebert 1996) with the same approach as described in Flury et al. (2022b). The τ values are estimated after removing the two outliers and the values in the bracket are including the outliers. The typical uncertainty in τ is ±0.11.
