Top: f_esc versus M_UV. The parent sample is shown with the pink dots, the high-confidence sample is shown by the dark diamonds, and the average f_esc in bins of M_UV is shown as the black squares. The mean f_esc does not show a trend with M_UV. The average f_esc of our sample is consistently measured between 10 and 15% in all bins. Bottom: fraction of sources with f_esc > 0.1 in each UV magnitude bin. This fraction also shows no trend with M_UV.
