Enclosed DM fraction, i.e., DM divided by the sum of baryonic matter from the scaled lens light and dark matter enclosed in radius r, of the models adopting a power law (bottom) or NFW (top) DM distribution. All models include the point mass in the lens center, which is not considered among the baryonic mass and thus not shown in this plot. For comparison, the value of the DM fraction within one effective radius of Spiniello et al. (2011) is shown by the horizontal solid line (for the value) and dashed lines (for 1σ uncertainties).
