Residuals of the stellar-mass prediction as a function of halo mass for GNNS04/T04 → S00/T00 at four redshifts. Points and error bars show the median and 16th–84th percentile range of the catalog-level median residuals in each halo-mass bin. The lower panels show the median number of galaxies per catalog in the same bins.
