Redshift formula for velocity
WebRedshifts can be measured very accurately. A typical velocity measurement for a galaxy might be 12,540 ± 120 km/s, which corresponds to a redshift of z = v / c = 12,540 / 3x 10 5 = 0.0418. The uncertainty in velocity corresponds to a redshift uncertainty of 120 / 3 x 10 5 = 0.0004, so we would quote the complete measurement as z = 0.0418 ± 0.0004. http://astronomyonline.org/Science/RelativisticRedshift.asp

In principle, if we measure distances and redshifts for objects at a variety of distances we could then infer a ( t) and k. The general relationship between redshift and luminosity distance is contained in these equations: (8.6) c ∫ a e 1 d a a 2 H = ∫ 0 d d r 1 − k r 2.
