Notes. Column 1 gives the name of the galaxy; Col. 2 gives the observed escape fraction of ionizing photons (; taken from the recalculations of Chisholm et al. 2017). Column 3 is the stellar continuum attenuation (EBV). Column 4 is the logarithm of the H I column density (NHI) derived from the O I 1039 Å absorption line and 12 + log(O/H) (except for J0925+1403 where O I is not detected; denoted with an H). Column 5 is the H I covering fraction () derived from the depth at line center of the Lyman series absorption lines, and Col. 6 is the Si II covering fraction (). Columns 3–6 are taken from Paper I. Column 7 is the predicted Lyman continuum escape fraction using the dust attenuation and (Eq. (5)). Column 8 is the Lyα escape fraction (; Verhamme et al. 2017) rescaled to an intrinsic flux ratio of Lyα/Hα = 8.7. The extinction-corrected [O III] 5007 Å/[O II] 3727 Å flux ratio (O32) is given in Col. 9 (Verhamme et al. 2017). We note that Tol 0400−381 and Mrk 54 have the detector gap over the Lyα line, thus they do not have a measured .
