Notes. (a) Spectral type range of the candidate ionizing stars including uncertainty in magnitudes and colors, (b)Hotal number of candidate ionizing stars in each spectral type category,(c) total Ly-photon rate calculated from all candidate stars considering them to be the latest spectral type in the category, (d)same as c but considering them to be the earliest spectral type in the category.
