Redshift evolution of the escape fraction of Lyman-α photons from LAEs in the A2744 lensing cluster colour-coded by the absolute UV magnitude of each LAE. The global medians of our sample and that in B11, are shown with red and cyan dashed lines respectively. The median uncertainty of the sample (∼18%) is shown by the black error bar, as if it was at the level of the global median, offset for clarity.
