TL;DR: In this paper, the first year of data from the differential microwave radiometers on the Cosmic Background Explorer was presented, and the angular autocorrelation of the signal in each radiometer channel and cross-correlation between channels were consistent and gave a primordial fluctuation power-law spectrum with index of 1.1 +/- 0.5, and an rms-quadrupole-normalized amplitude of 16 +/- 4 micro-K.
Journal ArticleDOI

Wilkinson +27 more
TL;DR: The techniques available for the identification and subtraction of sources of dynamic uncertainty from data of the Differential Microwave Radiometer (DMR) instrument aboard COBE are discussed in this article.
Journal ArticleDOI
COBE differential microwave radiometers - Calibration techniques
Charles L. Bennett,G. F. Smoot,Michael A. Janssen,Samuel Gulkis,A. Kogut,Gary Hinshaw,C. Backus,M. G. Hauser,John C. Mather,L. Rokke,L. Tenorio,Rainer Weiss,David T. Wilkinson,Edward L. Wright,G.

TL;DR: In this paper, the authors used the Doppler effect due to the earth's motion around the barycenter of the solar system as an external calibration source to calibrate the DMR.
Journal ArticleDOI

TL;DR: The concept and operation of the Differential Microwave Radiometers (DMR) instrument aboard NASA's Cosmic Background Explorer satellite are reviewed, with emphasis on the software identification and subtraction of potential systematic effects as mentioned in this paper.
Proceedings ArticleDOI
