Method

NumCosmoDataBaoEmpiricalFit2dget_alpha_perpendicular

Declaration [src]

gdouble
nc_data_bao_empirical_fit_2d_get_alpha_perpendicular (
  NcDataBaoEmpiricalFit2d* bao_ef,
  NcmMSet* mset
)

Description [src]

Calculates value of $\alpha_{\perp}$ given a NcmMSet, $$ \alpha_{perp} = \frac{[D_t(z)/r_d]}{[D_t(z)/r_d]_{fid}},$$ where $D_t(z)$ is the transverse comoving distance [nc_distance_transverse()], $r_d$ is the sound horizon [nc_distance_sound_horizon()] at the drag epoch, and ‘fid’ indicates fiducial.

Parameters

mset

Type: NcmMSet

A NcmMSet.

The data is owned by the caller of the method.

Return value

Type: gdouble

$\alpha_{\perp}$.
