Comparison between photometric and true redshifts, “true” redshifts being in this case the simulated redshifts as described in Sect. 2.1. The rows correspond to CEERS_1, CEERS_2, HUDF_1 and HUDF_2 observing strategies from top to bottom, and the columns represent observed NIRCam/F200W magnitude intervals. Color indicates the number of sources. The mean normalized residual, the normalized median absolute deviation and the catastrophic error fraction η for all the detected sources are indicated. The solid black line shows the 1:1 relation and the dashed black lines the ±0.15(1 + z_true) threshold used to compute η. The degeneracy between the Balmer 4000 Å break and the Lyα 1216 Å break is identified by the dotted-dashed red line, with 15% errors in dotted red lines.
