Types and Values

enum NcHIPrimAtanParams

Primordial adiabatic scalar power spectrum: $$ \mathcal{P}_{SA}(k) = \xi_\mathrm{neq}(k)\mathcal{P}_{\mathrm{F}}(k),$$ where $$ \mathcal{P}_{\mathrm{F}}(k) \equiv \mathcal{A}_\mathrm{s}\left(\frac{k}{k_\star}\right)^{n_s -1 } $$ and $$ \xi_\mathrm{neq}(k) = \arctan \left[ \left(\frac{k}{k_\mathrm{c}}\right)^\lambda + c_2\right] - \frac{\pi}{2} + c_3. $$

Primordial tensor power spectrum: $$ \mathcal{P}_T(k) = r \mathcal{A}_\mathrm{s} \left(\frac{k}{k_\star}\right)^{n_T -1 }.$$
