Left panel: observed Lyman continuum escape fraction () vs. the predicted Lyman continuum escape fractions made using the Si II covering fraction, derived from the Si II 1260 Å and Si II 1190 Å doublet. Right panel: escape fraction predicted by extinction correcting the Lyα escape fraction (). The and methods are consistent with the within 1.2 and 1.8σ, respectively. There are two fewer points because Lyα is in the detector gap for Tol 0440−381 and Mrk 54.
