Dependence of the ionizing photon output from galaxies (that is fesc(LyC) × ξion) as a function of UV magnitude (left) and Lyα equivalent width (right). The best-fitting linear relations are shown as blue lines (with considerable scatter in the relation, which is not shown to preserve clarity). Overall, we do not find any strong dependence of the ionizing photon output on either the UV magnitude of the Lyα strength. The ionizing photon output is key to quantifying the role of star-forming galaxies in contributing towards the reionization budget at z > 6.
