Distribution of measured Hα fluxes (corrected for flux loss following Cassata et al., in prep.) versus true Hα fluxes for the EDS-SF_sim (top) and EWS-SF_sim (bottom) simulated samples. Blue histograms show galaxies with accurate redshifts with |Δz|/(1 + z)≤0.003, red histograms indicate contaminants from mis-identified emission lines, and grey histograms represent contaminants from noise spikes.
