Fig. 7.
Bias on the mean redshift (see Eq. (3)), averaged over the 18 photometric noise realisations, under different σzp selection thresholds. Top panels: fraction of the sample retained after having applied different σzp thresholds. Middle and bottom panels: bias on the mean redshift using the direct calibration and de-biasing techniques, respectively. The left and right panels correspond to the DES/Euclid and LSST/Euclid configurations, respectively. We assume a SOM training sample with 2 galaxies per cell.
