Relation between galaxy number density and corresponding redshift error, as a function of redshift, ODDS cut, and galaxy color. Red galaxies, blue galaxies and the full sample are shown in red, blue, and black lines and symbols, respectively. Results are presented in redshift bins of Δz = 0.2, centred at z = 0.2 (circles), z = 0.4 (squares), z = 0.6 (diamonds) and z = 0.8 (pentagons). For each redshift, the symbols correspond to the cumulative number density for increasing cuts, at ODDS > 0.0, 0.2, 0.4, 0.6, 0.8, 0.9 (for some cuts the symbols are overlapping). The larger the size of the symbols, the larger the ODDS cut (thus the redshift precision). Dashed lines correspond to the regime where we have, in the miniJPAS field, less than 15 galaxies.
