Notes.
From Bergvall et al. (2006), Heckman et al. (2011), Leitet et al. (2013) plus Tol 1214−277 (Thuan & Izotov 1997; Mas-Hesse et al. 2003), and GP1291+15 (Cardamone et al. 2009), for which medium-resolution Lyα spectra are available. Below the horizontal line we also list four non-leakers from the sample of Heckman et al. (2011) for comparison.
