Lyα escape fraction as a function of rest frame Lyα equivalent width, stellar mass, UV absolute magnitude, reddening, UV β slope, and star formation rate. CEERS and JADES data are represented by circles and diamonds respectively. We report lower limits with black arrows, error bars are in grey instead. In the top-left panel, we show the fit relation found by Begley et al. (2024) in VANDELS z ∼ 4 − 5 data. In the middle-right panel, we show the best fitting relations found by Hayes et al. (2011), which exhibit a slight deviation from the trend proposed by Calzetti et al. (2000).
