Differences in age, metallicity, and extinction recovered by PYPIPE3D. The difference Δ is calculated as recovered-assigned for age and metallicity [dex] and as recovered-intrinsic for Av. The panels show the number density of galaxies of the differences across each parameter. The solid and dashed cyan lines show the mean and standard deviation of the differences, respectively, while the dashed magenta lines show 2σ deviations from the mean. An age-metallicity degeneracy is seen as PYPIPE3D tends to recover systematically younger ages and higher metallicities than expected. However, the recovered values are within the expected errors of 0.1 dex. As expected, extinction is increasingly underestimated as its value grows.
