Method

NumCosmoHICosmoVexpxe_tau

Declaration [src]

gdouble
nc_hicosmo_Vexp_xe_tau (
  NcHICosmoVexp* Vexp,
  const gdouble tau
)

Description [src]

Computes the value of $x_e$ at time $\tau$. Note that all interface implementations of perturbations use the observables computed at $x_\mathrm{e} = 1$, for example, the physical wave number $k$ at $\tau$ is $k_\mathrm{phys} = k x_\mathrm{e}$.

Parameters

tau

Type: const gdouble

$\tau$.

Return value

Type: gdouble

$x_\mathrm{e}$.
