Measurement of the cosmic microwave background spectrum by the COBE FIRAS instrument
Abstract
The cosmic microwave background radiation (CMBR) has a blackbody spectrum within 3.4 X 10^-8^ ergs cm^-2^ s^-1^ sr^-1^ cm over the frequency range from 2 to 20 cm^-1^ (5-0.5 mm). These measurements, derived from the FIRAS instrument on the COBE satellite, imply stringent limits on energy release in the early universe after t~1 year and redshift z~3 x 10^6^. The deviations are less than 0.03% of the peak brightness, with an rms value of 0.01%, and the dimensionless cosmological distortion parameters are limited to |y| < 2.5 x 10^-5^ and |μ| < 3.3 x 10^-4^(95% confidence level). The temperature of the CMBR is 2.726 +/- 0.010 K (95% confidence level systematic).

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.
