NED service to retrieve Quantities Derived from Redshift for a named object: The NASA/IPAC Extragalactic Database (NED) provides a comprehensive fusion of multi-wavelength data for hundreds of millions of objects located beyond the Milky Way galaxy. This service retrieves quantities derived from redshift for a named object. The following quantities are provided: - Calculated and corrected velocities: Heliocentric, Kinematic LSR, Galactocentric GSR, Local Group, 3K CMB, Virgo Infall, Virgo plus Great Attractor, Virgo + Great Attractor + Shapley Concentration - Hubble flow distance and distance modulus: applying the same corrections noted above, the Hubble distance in Mpc and the distance modulus in (m - M) magnitude units are provided - Scale at Hubble flow distance: applying the same corrections noted above, the scale is provided in units of pc/arcsec, kpc/arcsec, kpc/arcmin, and Mpc/degree - Cosmology-corrected quantities: Luminosity Distance [Mpc], Angular-Size Distance [Mpc], Co-Moving Radial Distance [Mpc], Co-Moving Tangential Distance [Mpc], Co-Moving Volume [Gpc^3], Light Travel-Time [Gyr], Age at Redshift (of the object) [Gyr], Age of Universe [Gyr], Scale (Cosmology Corrected) [pc/arcsec,kpc/arcsec,kpc/arcmin,Mpc/degree], Surface Brightness Dimming [Flux Density per Unit Area, Mag per Unit Area]
