Point estimates metrics results comparison for all the methods. Circles represent the spectroscopic sample and crosses are the L15 one. Top left: scatter (σ) versus outlier fraction (η) of all methods for the whole spectroscopic sample (12 463 sources). Top right: σ_USE = 1 versus η_USE = 1 for USE = 1 selected sources for each method (see Table B.1 for all the values). Bottom left: σ_Euclid versus η_Euclid for the Euclid selection (see Table B.2). Bottom right: σ_30-bands versus η_30-bands using the L15 photo-z as reference redshift plotted as crosses (see Table B.4 for all the values) and Euclid sample results weighted with the color-space weights to match the spectroscopic sample to the photometric one plotted as circles (see Table B.3). RF values are outside the limits of the plot for the L15 sample due to a large outlier fraction.
