Declaration [src]

gdouble
nc_hicosmo_qspline_mean_kappa (
  NcHICosmoQSpline* qspline
)

Description [src]

Gets the mean value of $q(z)$ curvature, i.e. the root-mean-square geometric curvature of $q(z)$ over $[0, z_f]$ (the $p = 2$,

NCM_SPLINE_CURVATURE_GEOMETRIC case of nc_hicosmo_qspline_lp_norm()).

Return value

Type: gdouble

The mean value of $q(z)$ curvature.
