double getOmegaK() const
Get the Omega curvature (computed as 1 - Omega_m - Omega_L) for the cosmology.
double getOmegaM() const
Get Omega matter for the cosmology.
CosmologicalParameters(double omega_m=0.3089, double omega_lambda=0.6911, double hubble_constant=67.74)
Constructor taking the cosmologycal parameters.
double getHubbleConstant() const
Get the Hubble constant H_0 in (km/s)/Mpc.
double getOmegaLambda() const
Get Omega Lambda for the cosmology.
Model the cosmological parameters. Omega_m, Omega_lambda, Omega_k and hubble_constant. Guarantee that the sum of the Omegas is 1.
