Near-infrared color–magnitude diagram of galaxies, J-Ks vs. Ks total magnitude. The RS fit, using the ten brightest galaxies, is shown by the solid black line. The dashed and dotted lines indicate ±3σ and ±5σ around the fit, respectively. The new cataloged galaxies are presented, color-coded by morphological classification. Galaxies from Du15 and 2MASX, with redshifts similar to that of the Ophiuchus cluster, are shown with open squares and open triangles, respectively.
