Comparison between measured and input stellar masses, for the CEERS_1 and HUDF_1 observing strategies (top and bottom figures, respectively). Each panel represents an input redshift interval centered at z_true = 1, 2, 3, … of width Δz = 1. Color indicates the number of sources in the whole sample, with the same color scale as in Fig. 10. The thick black contours represent the distribution of the sources with correct photometric redshift |z_phot − z_true|< 0.15z_true, including 68% and 95% of these sources, respectively. The median shift (Δ) and the NMAD (σ) for the sources with correct z_phot and 8 <  log(M_*, true/M_⊙) < 10 are indicated (in dex). The solid line shows the 1:1 relation and the dashed lines ±0.3 dex. The red arrows indicate the detected 90% stellar mass completeness.
