Size and magnitude of all sources and photometric redshift of the input galaxies. Left panel: r-band magnitude vs FWHM of the galaxies detected in miniJPAS and used for the analysis (in blue). Shown are objects with a “stellarity” Bayesian probability of being stars higher than 50% (in red) and of being galaxies lower than 50% (in blue). All objects (in green) with a FWHM smaller than the PSF size of each individual pointing plus a tolerance of 0.11 arcsec (indicated by the vertical lines) were rejected regardless their classification. Right panel: average redshift probability distribution of galaxies as measured by AMICO with a peak P(z) located at three different redshifts and for two different magnitudes: r = 20 and r = 22 (in blue and red, respectively). This estimate is produced by AMICO through the input photo-zs and is used in the cluster model construction. The black dashed lines show the typical uncertainty of photo-zs based on broad-band photometry.
