- distance_prior(redshift_prior, luminosity_distance, cosmology='Planck15_LAL')[source]
Calculate the prior on luminosity distance given a redshift prior assuming the given cosmology.
\[p(d_L) = p(z)\frac{dz}{dd_L}\]- Parameters:
- redshift_prior: callable
The redshift prior function.
- luminosity_distance: array_like
The luminosity distance values to evaluate the prior for.
- cosmology: str
The name of the cosmology, default is Planck15_LAL
