Number of wide‐separation lenses vs. the fraction of halo mass that is contained within a small fiducial radius (indicated in the label). Each point indicates a model with specific values of α and ﹩\mathrm{med}\,\,( C_{-2}) ﹩, with squares (triangles) for LCDM (SCDM). The filled circles indicate NFW (﹩\alpha =1﹩) models with ﹩\mathrm{med}\,\,( C_{-2}) =6﹩, 7, and 8. Lines connect models with ﹩\alpha =1﹩ and 1.5 (in the main relations) and ﹩\alpha =1.8﹩ and 1.9 (offset above the main relations). The horizontal lines indicate the 1 σ, 90%, and 95% confidence upper limits on the number of lenses.
