Model results for 13 galaxies. Left: NFW concentration vs. shear; center: virial mass vs. shear; right stellar baryon fraction vs. shear. The open squares represent the model without an adiabatically contracted dark matter halo (non-AC), and the filled circles represent the model with adiabatic contraction (AC). The vertical lines represent the measured shear (solid line) with the 1σ error added and subtracted (dashed lines).
