Illustration of the performance of the best-performing EAZY template set, namely v1.3 with all possible combinations of templates. Top panel: normalised redshift difference as a function of the F775W magnitude with the points plotted at the average magnitude and the median difference in each bin, and the error bars indicating the 16th and 84th percentiles of the distributions in x and y. The red points with error bars are shown where the outlier fraction exceeds 15%. Middle panel: same, but now plotted as a function of the observed F775W – F160W colour, and final panel: same but against the spectroscopic redshift. Note the one bin near z = 0.4 with very discrepant bias.
