Cosmological Parameters

Cosmological Parameters may be customized and used to correct the redshifts of objects returned by the search. Default values are Ho=73 km/s/Mpc, Omega(matter)=0.27, and Omega(vacuum)=0.73. Redshift values may be corrected to the CMB reference frame, corrected for Virgo Infall, for Virgo and Great Attractor Infall, or Virgo plus Great Attractor plus Shapley Infall.
