Left: UV β slope as a function of M_UV for galaxies in the redshift range 5 < z < 6.5 (circles), matching the selection in De Barros et al. (2017) (stars). The continuous black lines at M_UV = –21 and –18.75 mark the range considered. Galaxies with Lyα EW₀ > 25 Å are shown in blue, while the rest of the population is shown in red. The best-fit relation and 1σ uncertainty at z ∼ 6 from Topping et al. (2024) and Dottorini et al. (2025) are overplotted in black and green, respectively. Right: Cumulative distribution functions of Lyα EW₀ at z ∼ 6. The DB17 and JWST Lyα-break samples are shown as stars and circles, respectively. Error bars were computed following Gehrels (1986). The dashed black line shows the best-fit exponentially declining function to the DB17 data, corresponding to a case with no Lyα slit loss (T = 1). The dashed blue line and shaded blue region represent the JWST extracted CDF assuming T = 0.65 ± 0.10. The dashed red area indicates the EW₀ range where a direct comparison is not possible due to the JWST completeness limit.
