Cumulative fraction of escaping LyC photons per bin of virial mass in SPHINX-SN (red) and SPHINX-CR (dark blue), for data stacked between z = 15 and z = 7 (upper panel) and between z = 7 and z = 5 (lower panel). The shaded areas show the lower and upper masses for which halos respectively contribute to 25% and 75% of the total escaping LyC photon budget at the corresponding redshift range. Lower mass halos contribute the most to reionisation, especially in SPHINX-CR.
