EnzoCosmology.comoving_radial_distance(z_i, z_f)¶

The comoving distance along the line of sight to on object at redshift, z_f, viewed at a redshift, z_i.

Parameters:	z_i : float The redshift of the observer. z_f : float The redshift of the observed object.

Examples

>>> co = Cosmology()
>>> print co.comoving_radial_distance(0., 1.).in_units("Mpccm")
