Histograms of the Lyman α EW₀ of the full sample, including both MUSE-Wide and MUSE-Deep objects. The blue histogram shows the objects with a secure measurement (excluding lower limits), the green bars on top show the objects with a limiting EW₀. The exponential fits N = N₀ exp(−EW₀/w₀) are shown as the dashed lines, blue for the objects with secure measurements and light green for the full sample including lower limits. The bin width in EW₀ is 50 Å. For the measurement of the characteristic EW₀w₀ (given below the legend and in Table 4) the smallest EW₀ bin was excluded as it is likely incomplete (as Lyman α lines with small or zero line fluxes are hard to detect and preferentially result in small EW₀). The shaded areas around the dashed lines indicate the exponential fits for the EW₀ distributions using UV continuum slopes of β = −1.57 and −2.29, the first and last quartiles of the distribution of measured β values.
