Method

NumCosmoHIPertGWeval_powspec_at

Declaration [src]

gdouble
nc_hipert_gw_eval_powspec_at (
  NcHIPertGW* pgw,
  NcmModel* model,
  const gdouble tau
)

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: NcmModel

A NcmModel.

The data is owned by the caller of the method.
tau

Type: const gdouble

$\tau$.

Return value

Type: gdouble

The power spectrum of the tensor perturbation.
