Rough estimates for hydrogen- (Q0, top) and helium-ionizing (Q2, bottom) emission rates. The total rates are shown as a sum of rates for single stars, low-mass stripped stars whose rates are calculated via interpolation (M < 8.5 M⊙), and higher-mass stripped stars whose rates are calculated via extrapolation (M > 8.5 M⊙). We did this calculation separately in the case that there is no drop (left) and in the case that there is a drop (middle), and we show the estimate from BPASS for comparison (right).
