Here we present supplementary numerical data for the CBI observations reported by A. C. S. Readhead et al. (2004 ApJ, 609, 498-512, preprinted as astro-ph/0402359). If you use these data in a publication, please cite the appropriate papers and also give the URL of this web page and the date of publication (given at the bottom of this page).
The CBI even binning data (bins 2 to 14) formatted for use with the COSMOMC Markov Chain Monte Carlo package (Lewis & Bridle 2002, Phys. Rev. D, 66, 103511) can be found in the compressed tar file CBI2.0_newdat.tgz (revised 2006 Aug 25). Note: this replaces the file cbi2.0.tgz (revised 2004 Mar 3), in which the Fisher matrix was incorrectly transformed for the offset-lognormal approximation. Thanks to Loison Hoi for pointing out the error. For more information, see the discussion in the CosmoCoffee CMB forum.
The CBI 2000+2001 data have been scaled to a 32 GHz Jupiter temperature of 147.3 ± 1.8 K. This is a weighted mean between the WMAP 32 GHz value and the OVRO absolute measurement (see the paper).
The CBI overall calibration error should be taken as 1.3% in flux density (2.6% in power).
Band power measurements are given in Table 1 of Readhead et al. There are two alternate binnings of the power spectrum, which are not independent. We recommend use of the even binning, reproduced here. Bins 1 and 15 were not used in the parameter analysis of Readhead et al.

See Figure 5 of Readhead et al. The even window functions are tabulated in file total_joint-tot_x50_a_even-win.txt . This file has 15 columns, one for each bin (1...15), and 4599 rows, for l = 2...4600. The numbers tabulated are WB(l), but are not normalized:
