Lyα observables (top panel: L_Lyα; middle panel: EW_Lyα; bottom panel: $f_{\text{esc}}^{\text{Ly}\alpha }$ ) vs. galaxy inclination. Filled purple symbols are based on the kinematical inclination, i, from the disc modelling of the RDs with GalPak^3D. Unfilled symbols are based on photometric inclinations (purple: RD; green: PR) according to cos(i)≈(b/a)_I, where (b/a)_I is the I-band axis ratio from Rasekh et al. (2022). Thus, each RD is represented by a filled and an open symbol in these plots. Circles with error bars indicate measurements of the Lyα observables, whereas downward-pointing triangles indicate upper limits. Correlation coefficients (Kendall’s τ) and corresponding p-values for the kinematical inclinations are provided in the top-right corner of each panel.
