Photometric vs. spectroscopic redshifts for galaxies in the cluster field and in the magnitude range 18 ≤ R_C ≤ 24 mag. Black dots are spectroscopically confirmed members. The two dashed lines represent the criteria in photometric redshifts chosen to classify the cluster members. Galaxies within this range of photometric redshift are colored in red. Galaxies with z_phot in this range and without spectroscopic information are classified as members. Blue crosses are galaxies outside both the spectroscopic and photometric selections.
