Caption: Figure 9.
The left panel shows the redshift versus stellar mass for valid sources in F444W in the UNCOVER/MegaScience photometric catalog (use_phot = 1; gray) and all sources with a great or robust fitin F444W from this work (use_fit = 1 or 2; red). The right panel shows the net completeness of our fits in F444W, binned by redshift and stellar mass. We define completeness as the fraction of use_fit = 1 or 2 sources among use_phot = 1 sources. We omit any bins containing fewer than 10 use_phot = 1 sources. Overall, we achieve >80% net completeness at M* > 108M⊙ and z < 2; M* > 108.5M⊙ and 2 < z < 4; M* > 109M⊙ and 4 < z.
