f_esc versus β_UV slope. The darker diamond points highlight the high-confidence sample, while the dots represent the parent sample. The squares represent the average f_esc in β_UV bins, calculated from the parent sample. The f_esc − β_UV relation from Chisholm et al. (2022) is shown as the dashed line, with the uncertainty shown as the shaded area. With the dotted line, we show the results of Jaskot et al. (2024a), using the LyCsurv code (Flury et al. 2024). The average f_esc decreases as the β_UV slope becomes bluer.
