Deviations in the mean redshift (top) and the redshift standard deviation (bottom) for the ten Flagship2 tomographic bins relative to the true-redshift distributions using the SSM method. The deviations are shown for each bin and sky patch. We consider patches of 2500 deg² for the first two bins, and 1000 deg² for the others. The Euclid requirements on the uncertainty are highlighted by the shaded area centred around zero. The uncertainties are consistent across all the bins for the mean redshift and we achieve a clear improvement from previous work shown in red. For the redshift standard deviations, the uncertainties are slightly underestimated, but this is within an acceptable range given the requirements.
