Results of the SED-fitting photometric redshifts estimate using (from top to bottom): (i) ZPHOT and the true fluxes of the input catalog; (ii) ZPHOT and fluxes measured on the H band simulated image; (iii) ZPHOT on GOODS-South ASTRODEEP data. The plot shows the estimated redshifts versus the true redshifts from the input catalog (top and central panel); the redshifts estimated with the 13 bands used in the simulations versus the ones in the ASTRODEEP 43 bands catalog (Merlin et al. 2021, bottom panel).
