Fraction of QSOs in the candidate sample from the mock at 2.05 < z < 3.75. We represent our estimation of the QSO fraction (green solid line and green shaded area for 1σ uncertainty) based on the power-law fit to our Lyα LF and the SFG Lyα LF of Sobral et al. (2018). We also show the QSO fraction extracted from our mocks (blue solid line). We compare our results to previous realizations from past works.
