Validation of photometric redshifts (photo-zs) computed with two codes, EAZY and LePhare, in three bins of apparent HSC i magnitude. The black solid line represents a one-to-one relation, and the dashed lines enclose the photo-z at ±0.15(1 + z_spec) representing galaxies typically considered non-outliers. The fraction of sources outside the dashed lines (denoted η) and the precision measured with the normalised absolute deviation (noted σ_NMAD) are indicated in each panel. Top: comparison between photo-zs and spec-zs. Galaxies shown are those from the EDF-F spectroscopic sample from GOODS-S (Garilli et al. 2021; Kodra et al. 2023). The photo-z measurements of EAZY are displayed as orange circles, while the photo-z measurements of LePhare are displayed as blue circles. Bottom: comparison between photo-zs as calculated with the two codes for the full sample of galaxies in EDF-F. The EAZY photo-zs are displayed along the x-axis while the LePhare photo-zs are displayed along the y-axis. Bin colouring increases on a logarithmic scale.
