Notes. The Lyα equivalent width, EW(Lyα), is given in the rest-frame. The EW uncertainties are estimated as ± 20 Å. The last column contains the star formation rate per unit area, ΣSFR, in M yr-1 kpc-2. Columns 2, and 810 are taken from Izotov et al. (2016a,b). Note that has been recalculated from Izotov et al. (2016a,b), without SDSS vs. COS aperture correction, for comparison with other samples (see text for more details). The typical uncertainties on velocity shift measurements are ±10 km s-1 (see text for more details).
