Atacama Cosmology Telescope (ACT)

Product Name
CMB Chains 2008 Data


These are MCMC chains run using the ACT likelihood software based on the small-scale microwave power spectrum measured from the 2008 Southern sky survey. The chains also use the WMAP 7-year likelihood, and if indicated also include BAO and Hubble constant data.

The format of the chains is the same as for WMAP and the chains can be analysed using the Cosmomc patch given in http://lambda.gsfc.nasa.gov/product/map/dr4/getdist_get.cfm
