Cumulative distribution of the population distribution of the escape fraction. Shown are the median CDF for the exponential model inferred in this work (in orange; the shaded region marks the 16th and 84th percentile interval) and the eCDF for a selection of SPHINX galaxies (in black) with somewhat similar properties to our observed sample. For context, the CDF for selections of red high-mass galaxies and blue low-mass galaxies in SPHINX are plotted. All selections are described in Sect. 6.2.
