FUNCTION fCosmoDl

Returns the luminosity distance at a given redshift.

Parameters:

@z float: redshift
@OmegaM float: matter density. If set as DEFAULT, then 0.27891507
@OmegaL float: dark energy density. If set as DEFAULT, then 0.721
@OmegaR float: radiation density. If set as DEFAULT, then 8.493e-5
@omega0 float: dark energy state equation. If set as DEFAULT, then -1
@h_0 float: (hubble constant[Km/s/MPc])/(100[Km/s/MPc]). If set as DEFAULT, then 0.701 Reference: http://lambda.gsfc.nasa.gov/product/map/dr3/pub_papers/fiveyear/cosmology/wmap_5yr_cosmo.pdf

returns Dl float: luminosity distance in MPc.
select dbo.fCosmoDl(0.1,0.27891507,0.721,8.493e-5,-1,0.701); select dbo.fCosmoDl(0.1,DEFAULT,DEFAULT,DEFAULT,DEFAULT,DEFAULT)
return 460.365188862815 and 460.365188862815
