COSMOMC: CMB datasets ......

Post by Jun-Qing Xia » August 21 2005

Dear all,

There are severl CMB datasets in the code. When use_CMB = T and using the datasets of ACBAR_lge800_.dataset, CBI2.0_lge600.dataset and VSA_lge600.dataset except WMAP which power spectra these datasets relate to? TT, TE or EE? And which power spectra are used when using these CMB datasets to calculate the likelihood of CMB?

Thanks!

It uses the published TT datasets for Kuo et al, Dickinson et al and Readhead et al, with points with l<600 cut to avoid cosmic variance coupling. Only the .newdat format alows TE and EE spectra to be used (WMAP is an exception as it uses a specially crafted code) - see the latest cosmomc release with latest boomerang data as an example.
