Bases: object

class figaro.cosmology.CosmologicalParameters_astropy(h, om, ol, w0, w1=0, w2=0)[source]

Bases: object

Wrapper for Astropy functions in a single class.

Parameters:

  • h (double) – normalised hubble constant h = H0/100 km/Mpc/s

  • om (double) – matter energy density

  • ol (double) – cosmological constant density

  • w0 (double) – 0th order dark energy equation of state parameter

  • w1 (double) – 1st order dark energy equation of state parameter (backward compatibility)

  • w2 (double) – 2nd order dark energy equation of state parameter (backward compatibility)

Returns:

instance of CosmologicalParameters class

Return type:
