True vs. estimated richness for the 1208 halos in our sample. Richness refers to galaxies brighter than H∗(zp) + 1.5 and within r200 radius of each halo. Galaxies with a statistical photometric redshift accuracy σ0 = 0.03 are considered. Left: richness is estimated as Nestimated, where Pthr = 20% is considered. Right: richness is estimated as the sum of the membership probabilities. The mean logarithmic difference along with the rms dispersion around the mean are reported in the panels.
