Abstract
Photometric surveys are quite complete (the number of galaxies can reach ~10^{-2} h^3 Mpc^{-3}), but the quality of photometric redshifts implies, in practice, a complex selection of galaxy populations that can effectively be used by these surveys. In order to study the completeness of these surveys, it is useful to compare them to others, deeper and/or spectroscopic. In 2024 we had the r…
