Class
NumCosmoDataBaoEmpiricalFit2d
Description [src]
final class NumCosmo.DataBaoEmpiricalFit2d : NumCosmoMath.DataDist2d
{
/* No available fields */
}Baryon oscillation data — $D_H / r_d$ and $D_t / r_d$ empirical likelihood.
This object implements the BAO data when its likelihood function is provided, e.g., [Bautista et al. (2017)][XBautista2017].
The data is stored in a NcDataBaoEmpiricalFit2d object. The data is stored in a
NcmDataDist2d base class object, which is a subclass of NcmData. The data
represents the likelihood function of the transverse distance $D_t$ and the Hubble
distance $D_H$ at the redshift $z$ divided by the sound horizon at the last
scattering surface $r_s$. The likelihood function is provided as a NcmSpline2d
object.
Instance methods
nc_data_bao_empirical_fit_2d_get_alpha_parallel
Calculates value of $\alpha_{\parallel}$ given a NcmMSet.
nc_data_bao_empirical_fit_2d_get_alpha_perpendicular
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.
