Number density of galaxies with stellar masses > 10^10.2 M_⊙ in the 10 GCLASS clusters as a function of radial distance. The total galaxy population (black) is separated between star-forming (blue) and quiescent (red) galaxies. Thick points show the membership-corrected number density, where the error bars represent the uncertainties that arise from membership correction. The points are fitted by projected NFW functions (lines), with different concentration parameters. The lower panel shows the fraction of galaxies in each bin with a spectroscopic redshift.
