Statistics of photo-z values as a function of i-magnitude. The GAMA galaxies within the wide dataset were used for calculating statistics. From the first row in the figure, we plotted the statistics from the SPHEREx full-sky, 7DS WTS, 7DS RIS, and combined SPHEREx full-sky + 7DS WTS data from the first row to the bottom. The statistics from different methods are plotted with different colors, which are noted in the legend. The shaded region interpolates the confidence intervals of the bins.
