Collection of measurements of absolute escape fractions of known LyC emitters as a function of galaxy UV luminosity. The LGRB lines of sight studied in this paper are shown with red stars. Other data points are taken from Fletcher et al. (2019) (z ∼ 3, light green), Izotov et al. (2016, 2018a,b) (z ∼ 0.3, violet), Ji et al. (2020) (z ∼ 3.8, dark green) and Vanzella et al. (2016) and Shapley et al. (2016) (z ∼ 3.2, blue). Black lines indicate the limit and the average as provided by the z ∼ 3 sample study of Steidel et al. (2018). The inset shows the redshift distribution of the systems.
