Notes. Column (1) is the name of the galaxy, Col. (2) is the stellar mass (M_∗), Col. (3) is the star formation rate (SFR), Col. (4) is oxygen-to-hydrogen abundance (log(O/H) + 12), Col. (5) is the redshift (z), Col. (6) is the O₃₂ = [O iii] 5007 Å/[O ii] 3727 Å flux ratio, Col. (7) is 50% of the Petrosian radius measured from the COS acquisition images (R), and Col. (8) is the LyC escape fraction (). R is not measured for the two Leitherer et al. (2016) galaxies because COS images are not available. We include the FUSE galaxy, Haro 11 as a LyC candidate. Notes on the re-measurement of the from the COS spectra are given in the appendix. Column (9) gives previous references for the COS spectra of each galaxy.
