Observational properties of the galaxies in the cluster. First panel: redshift (PHOTOZ) distribution. The median (μ) and standard deviation (σ) of PHOTOZ are written in the figure. The black dashed line represents the median of PHOTOZ. Second and third panels: distributions of the r_SDSS magnitude, and median S/N of the narrow-band filters. Fourth panel: median MAG_PSFCOR S/N in the narrow-band filters as a function of r_SDSS magnitude. Colour coding indicates the probabilistic association given by AMICO.
