WMAP DR4 Recommended Parameters Constraints

The data made available through this page has been updated. The most recent version of this data may be accessed through https://lambda.gsfc.nasa.gov/product/wmap/current/"

The tables below contain the cosmological parameters recommended by the WMAP Team after the seven-year WMAP data release. Each table assumes a standard 6-parameter LCDM model accounting for the effects of gravitational lensing and the Sunyaev-Zeldovich effect. The first table gives constraints using only WMAP data, the second table additionally includes the BAO angular diameter distance measurement, and a local measurement of the Hubble constant. Readers interested in fundamental parameters beyond the standard 6 LCDM parameters should visit the Cosmological Parameter Table. Click on the graphic to retrieve a Postscript version.
