Same as the top panel of Fig. 4, but including scatter in the concentration of NFW halo profiles. Each panel corresponds to one out of a hundred random realizations, whereby the host halo of each galaxy is assigned a random value of concentration drawn from a lognormal distribution with σ_log 10c = 0.1 dex, centered on the mean mass-concentration relation in a Planck cosmology (Dutton & Macciò 2014).
