AGN/QSO fraction as a function of luminosity for each NB. We estimated this quantity by assuming that our results are entirely dominated by AGNs/QSOs and that the best Schechter fit of Sobral et al. (2018a) describes the distribution of SF LAEs (see Eq. (14)). Our results are in agreement with the spectroscopic determination of Sobral et al. (2018b), which only employs Lyα emission pre-selection for their targets. On the other hand, the estimates of Matthee et al. (2017b) and Calhau et al. (2020) are based on the detection of either X-ray or radio counterparts for their Lyα-emitting candidates.
