Cumulative distribution for Lyα REW for UV-faint galaxies (−20.25 < M_UV < −18.75) at z ∼ 7. Each solid line shows the expected distribution for a model with N_HI = 10²⁰ cm⁻² and a wind speed of 200 km s⁻¹, but with a different neutral fraction (Pentericci et al. 2014). Estimates from the literature (Ono et al. 2012; Schenker et al. 2012, 2014; Pentericci et al. 2014, 2018) are shifted by 1 Å for visibility. Our P(REW > 25 Å) point (grey) is likely affected by low completeness.
