Confidence intervals for the expected number of z ~ 6 optically selected quasars detectable by eROSITA in eFEDS. These predictions are derived from the UV QLF presented in Kulkarni et al. (2019), for a fixed α_ox − L₂₅₀₀ relation (Lusso et al. 2010) and deviations therefrom. The eFEDS sensitivity is accounted for. The vertical line shows the magnitude limit of the SDSS main survey sample of Jiang et al. (2016). The horizontal line marks the single detection limit. Within 1σ of the typical α_OX the detection of SDSSJ08 in eFEDS is consistent with predictions from optical surveys.
