Bases: object

Cosmology object, stores primary and derived cosmological parameters.

Parameters

  • Omega_c – float representing the cold dark matter density fraction.

  • Omega_b – float representing the baryonic matter density fraction.

  • h – float representing Hubble constant divided by 100 km/s/Mpc; unitless.

  • n_s – float representing the primordial scalar perturbation spectral index.

  • sigma8 – float representing the variance of matter density perturbations at an 8 Mpc/h scale.

  • Omega_k – float representing the curvature density fraction.

  • w0 – float representing the first order term of dark energy equation.

  • wa – float representing the second order term of dark energy equation of state.
