Fraction of recovered flux of unresolved sources as a function of true redshift (x-axis) and normalized redshift uncertainty (dashed lines in color). The triangle and crossed lines are the fractions for our selected galaxies in the 11 < log M_*(M_⊙) < 12 and 9.5 < log M_*(M_⊙) < 11 stellar mass bins, respectively. The impact of photometric redshift uncertainty is only a few percent for high stellar mass galaxies that contribute most of the unmasked signals.
