TL;DR: An analysis of all data taken by the BICEP2 and Keck Array cosmic microwave background (CMB) polarization experiments up to and including the 2014 observing season yields an upper limit r_{0.05}<0.09 at 95% confidence, which is robust to variations explored in analysis and priors.

TL;DR: The first season of observations with the Degree Angular Scale Interferometer (DASI) was conducted at the South Pole in the austral summer 1999-2000, and observations throughout the following austral winter.

TL;DR: In this article, the authors present measurements of anisotropy in the Cosmic Microwave Background (CMB) from the first season of observations with the Degree Angular Scale Interferometer (DASI) and find no evidence of foregrounds other than point sources in the data.

TL;DR: Using the Cosmic Background Imager, a 13-element interferometer array operating in the 26-36 GHz frequency band, the authors observed 40 deg (sup 2) of sky in three pairs of fields, each approximately 145 feet x 165 feet, using overlapping pointings.
