The curves are such that they best fit the data. The power spectrum predicted with the positive value n=0.0001 is totally excluded by the data.

Only very small values of n are possible when $\Omega _{\rm m0}\approx 0.224$ , the value of the CDM density parameter in agreement with CMB data of WMAP.
