Redshift of AMICO clusters. The data are based on the median miniJPAS photo-z of the galaxies with probabilistic association P > 0.5 (blue circles) and within 10′ from the detection centre compared with the spectroscopic redshift based on DEEP3 data. The uncertainty of our redshift estimates is σ_z = 0.0037(1 + z) (horizontal dotted lines), which is approximately ten times better than typically achieved with photometric surveys. The improvement of the redshift estimate based on the AMICO probabilistic memberships over the original output (small grey circles) is visible.
