Declaration [src]
gdouble
nc_hipert_adiab_eval_powspec_Psi_at (
NcHIPertAdiab* adiab,
NcmModel* model,
const gdouble tau
)
Description [src]
Evaluates the power spectrum of the gauge invariant variable $\Psi$ at a given time $\tau$. The power spectrum is given by $$ P_\Psi = u^2\frac{2\pi^2}{k^3} \frac{J_{22}}{2}. $$.
Parameters

Type:
NcmModelA
NcmModel.The data is owned by the caller of the method. tau-
Type:
const gdouble$\tau$.
