Observations of Large-Scale Anisotropy in the 3 K Background Radiation
Published online by Cambridge University Press: 14 August 2015
Abstract
Measurements of the background radiation were made at 8000 MHz with a beamwidth of 15 deg. Two antennas were used, arranged such that the equipment recorded the temperature difference between points five hours apart in right ascension and at declination + 32°. Data were taken only at night and at 3800 m altitude, in order to reduce systematic effects as much as possible. Two observing runs six months apart were combined; after subtracting Galactic non-thermal radiation, the remainder shows a significant dipole anisotropy, a possibly significant quadrupole anisotropy, and no detectable variations of smaller angular size: (Table I.)
