Left: Comparison of the dark matter rotation curve for different values of ﹩\Upsilon _{*}﹩ with the NFW rotation curves expected from cosmology for F568‐3. Right: Total dark matter mass as a function of radius for ﹩\Upsilon _{*,\mathrm{POP}\,}﹩. The solid line represents the dark matter mass predicted by CDM; the dashed line represents the dark matter mass allowed by the data. The two curves have been forced to meet at large radii; interior to this, CDM predicts more mass at all radii than is actually observed.
