Left: stacked photometric redshift probability distribution (sum of individual sources) of the optically cross-matched sample of the NB921 and NB816 LAE catalogues from D20. Right: histograms of the best-fitting solutions for SED fits performed with fixed-redshift solutions corresponding to the three candidate emission lines. The known possible redshifts from the NB emission line detections and more detailed SED fitting allows us to exclude other high-z solutions that are sometimes favoured by the photometric redshift code.
