h0 = 0.703

H0_SI = h0* 100000/(1000000* LAL_PC_SI)

DH_SI = LAL_C_SI/ H0_SI

Integrand used in many cosmography integrals. 1 / E(z) in Hogg's notation. |
Comoving distance (transverse) at z. Hard-coded for OmegaR = 0. |
Compute the redshift from a luminosity distance. Use the Newton-Raphson refinement method on a first-order guess. |
Different volume element per unit redshift. Hard-coded for OmegaR = 0. |
Analytical integration of dVdz. Hard-coded for OmegaR = 0. Double precision craps out below about 100 kpc (z=2.3e-6). |
Analytical integration of dVdz. Hard-coded for OmegaR = 0. Sped up for the case that you have D rather than (or in addition to) z. Double precision craps out below about 100 kpc (z=2.3e-6). |
