Density profiles of satellites, shown in bins of 4′′ (~35 kpc at z ~ 1.8) for clarity. Clockwise from the top left: B- and K_s-band flux, SFR and stellar mass. The best-fit β-model, shown with its associated uncertainties by the red line and orange envelope, was derived from the unrebinned data. The dashed vertical line marks the average putative virial radius of the halos and the level of contamination by interlopers (i.e., “background”) is shown in green.
