A Measurement of the Angular Power Spectrum of the Anisotropy in the Cosmic Microwave Background
Open accessAbstract
We report on a measurement of the angular power spectrum of the anisotropy in the cosmic microwave background (CMB). The anisotropy is measured in 23 different multipole bands from l = 54 (≈ 3°) to l = 404 (≈ 0 45) and in six frequency bands from 26 to 46 GHz over three observing seasons. The measurements are consistent from year to year. The frequency spectral index of the fluctuations (measured at low l ) is consistent with that of the CMB and inconsistent with either dust or Galactic free-free emission. Furthermore, the observations of the MSAM1-92 experiment (Cheng et al. 1994) are repeated and confirmed. The angular spectrum shows a distinct rise from δ T l ≡ [ l (2 l +1)⟨| a m l | 2 ⟩/4π] 1/2 =49 + 8 −5 μK at l = 87 to δ T l =85 + 10 −8 μK at l = 237. These values do not include an overall ±14% (1 σ) calibration uncertainty. The analysis and possible systematic errors are discussed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
