Lyman-α EW (EW_Lyα) distribution for all our samples. Objects selected as LAEs or LBGs are denoted by larger stars, LAE+continuum by smaller stars, LAE-only by upward pointing triangles, and LBG-only by downward pointing triangles. EW_Lyα values for the latter two populations are calculated using the upper limits of the continuum and Lyman-α flux, respectively. The objects are colour-coded by M₁₅₀₀. The horizontal dashed line demarcates the 25 Å level, above which LAEs are included in the calculation of the LAE fraction. Error bars are omitted for clarity, but shown in Figs. 4 and 5.
