The Dipole Observed in the COBE DMR 4 Year Data
Open accessAbstract
The largest anisotropy in the cosmic microwave background (CMB) is the ~3 mK dipole assumed to be due to our velocity with respect to the CMB. Using the 4 year data set from all six channels of the COBE Differential Microwave Radiometers (DMR), we obtain a best-fit dipole amplitude 3.358 +/- 0.001 +/- 0.023 mK in the direction (l, b) = (264.31^deg^ +/- 0.04^deg^ +/- 0.16^deg^, +48.05^deg^ +/- 0.02^deg^ +/- 0.09^deg^), where the first uncertainties are statistical and the second include calibration and combined systematic uncertainties. This measurement is consistent with previous DMR and FIRAS results.

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.
