Relations between ionised gas kinematics (v_shear, ${\sigma }_0^{\text{obs}}$, v_shear/σ₀^obs in the top-, middle-, and bottom row, respectively) and Lyα observables (EW_Lyα, $f_{\text{esc}}^{\text{Ly}\alpha }$, and L_Lyα, in the left-, centre-, and right column, respectively). Symbols are the same as in Fig. 6; additionally here upper limits in the Lyα observables are shown as leftward-pointing triangles. Correlation coefficients (Kendall’s τ) and corresponding p-values are provided in the top-right corner of each panel.
