gdouble
nc_hipert_adiab_eval_powspec_zeta_at (
NcHIPertAdiab* adiab,
NcmModel* model,
const gdouble tau
)
Description [src]
Evaluates the power spectrum of the gauge invariant variable $\zeta$ at a given time $\tau$. The power spectrum is given by $$ P_\zeta = u^2\frac{k^3}{2\pi^2} \frac{J_{11}}{2}. $$ where $u$ is the numerical factor for the power spectrum of the adiabatic mode, $k$ is the wave number.
