In addition to the DMR and DIRBE, another instrument using in this experiment was the Far Infrared Absolute Spectrophotometer, which demonstrated that a certain phenomenon was a black body with temperature of about 2.7 Kelvin.
This experiment made a more detailed measurement of the same signal as the RELIKT-1 experiment, which had operated in a band centered on 37 GHz. One instrument utilized during this experiment mapped the absolute sky brightness in 10 wavelength bands, while another instrument was a differential radiometer, whose measurements would later be repeated by experiments such as TopHat and BOOMERanG. In addition to the DMR and DIRBE, another instrument using in this experiment was the Far Infrared Absolute Spectrophotometer, which demonstrated that a certain phenomenon was a black body with temperature of about 2.7 Kelvin. Succeeded by the WMAP satellite, for ten points, identify this satellite experiment which measured the spectrum and the small-scale anisotropy of the CMB, and won a Physics Nobel in 2006 for George Smoot and John Mather.
