Observed Lyman continuum escape fraction () vs. the predicted Lyman continuum escape fraction () computed using the observed H I absorption properties and Eq. (5). The solid line shows a one-to-one relation, indicating that the predicted values are within 1.4σ of the observed Lyman continuum escape fractions. We note that there are two outliers more than 3σ from the one-to-one relation: Tol 1247−232 (at ~ 0.05 and ~ 0.005) and J1503+3644 (at ~ 0.01 and ~ 0.06). These outliers are discussed in Sect. 3.
