However, this analysis relies on assumptions about the initial power spectrum, which is usually taken to be a featureless power-law, P(k) ~ k^{n_s-1}. Many inflationary models predict power spectra with non-power law features. We discuss the possibility for detecting such features by describing the power spectrum as bins in k-space.
