The stellar-to-halo mass relation (SHMR) for BOSS CMASS galaxies using the PCA stellar mass estimates. The solid green curve shows the mean ﹩{M}_{* }﹩ in bins of ﹩{M}_{\mathrm{halo}}﹩, with the dashed curves indicating the 0.18 dex in scatter of the best-fit relation. The colored circles show the mean ﹩{M}_{\mathrm{halo}}﹩ in the observed bins in ﹩{M}_{* }﹩ used in this paper. Error bars indicate the inner 68% of the distribution of ﹩\mathrm{log}{M}_{\mathrm{halo}}﹩ in each bin. The gray shaded region indicates the number of halos, scaled as ﹩\mathrm{log}{N}_{h}﹩, at each point in this 2D parameter space.
