Comparison of our data with the relation found by Gazagnes et al. (2020) between f_esc(LyC) and the fraction of the flux at the trough of Lyman-α and the continuum flux. The shaded gray area represents the error on the relation. The empty red diamonds are the known leakers used by Gazagnes et al. (2020) to derive this relation. Many of our points fall on their relation but mostly for low escape fractions, whereas high escape fractions are often underestimated.
