Fraction of galaxies satisfying accuracy limits. Different limits are shown on the x-axis with the J-PAS target accuracy of 0.3% indicated with a dashed vertical line. Colours show different TOPz runs using various setups described in this paper and grey corresponds to the LePhare photo-z estimations presented in the miniJPAS database. This plot shows how correcting the observations and adding photo-z priors improve the results significantly. Galaxies with r < 22 mag and TOPz output z_wld were used.
