Description
The acoustic scale is defined as
$$ A \equiv D_V (z) \frac{\sqrt{\Omega_m H_0^2}}{z c},$$
where $\Omega_m$ is the matter density parameter [nc_hicosmo_Omega_m()
], $c$ is the speed of light [ncm_c_c()
],
$H_0$ is the Hubble parameter [nc_hicosmo_H0()
] and $D_V(z)$ is the dilation scale [nc_distance_dilation_scale()
].
See Section 4.5 from Eisenstein et al. (2005).
