Tentative plots of the escape fraction against various properties of the galaxies. The rhombs symbolize galaxies where f_esc was measured directly on the Lyman continuum, the triangles galaxies where f_esc was estimated using the residual flux in the C ii λ1036Å line. Filled symbols represent galaxies with Lyα in emission, open symbols galaxies with Lyα in absorption. The f_esc errors are plotted for 1σ. An abridgment marking the positions of the most interesting galaxies are also shown. In panel a) f_esc against the intrinsic absorption. The hatched line shows the position of Tol 1247-232 for the range of E(B − V)_i = 0 − 0.21 as described in the text, b) f_esc against the oxygen abundance, c) f_esc against stellar mass [ℳ_⊙], d) f_esc against H i mass related to the number of ionizing photons via L_B (solar units), e) f_esc against Lyα equivalent width, and f) f_esc against the specific star formation rate (SFR/ℳ_⋆).
