dV

zdm.cosmology.dV(z)

Comoving volume element per unit redshift per steradian.

Computes dV/dz/dOmega, the differential comoving volume element. This does not include any time dilation factor for rate conversions.

Parameters:

z (float) – Redshift.

Returns:

Volume element in Mpc^3 per unit redshift per steradian.

Return type:

float
