Declaration [src]
NcmSpline*
nc_hipert_gw_eval_powspec (
NcHIPertGW* pgw,
NcmModel* model,
const gdouble tau,
GArray* k_a
)
Description [src]
Evaluates the power spectrum of the tensor perturbation at a given time $$ P_h = u^2\frac{k^3}{2\pi^2} \frac{J_{11}}{2}. $$ where $u$ is the numerical factor for the power spectrum of the tensor mode, $k$ is the wave number.
Parameters
model-
Type:
NcmModelA
NcmModel.The data is owned by the caller of the method. tau-
Type:
const gdouble$\tau$.
k_a-
Type: An array of
doubleAn array of wave numbers.
The data is owned by the caller of the method.
Return value
Type: NcmSpline
The power spectrum of the tensor perturbation.
| The caller of the method takes ownership of the returned data, and is responsible for freeing it. |
