We present an improved analysis of the final data set from the QUaD experiment. Using an improved technique to remove ground contamination, we double the effective sky area and hence increase the precision of our cosmic microwave background (CMB) power spectrum measurements by ~30% versus that previously reported. In addition, we have improved our modeling of the instrument beams and have reduced our absolute calibration uncertainty from 5% to 3.5% in temperature. The robustness of our results…

Radical Compression of Cosmic Microwave Background Data
TLDR
This work presents a method for approximating the likelihood that takes power spectrum constraints, e.g., "band-powers," as inputs and advocates the calculation of this third quantity by experimenters, to be presented along with the maximum-likelihood band-power and variance.
Detection of polarization in the cosmic microwave background using DASI
TLDR
The detection of polarization of the CMB with the Degree Angular Scale Interferometer (DASI) is reported, and its level and spatial distribution are in excellent agreement with the predictions of the standard theory.
