New Measurements of the Cosmic Background Radiation Temperature at 3.3 Millimeter Wavelength
Abstract
The results of measurements of the cosmic background radiation (CBR) at 3.3 mm are reported, and the instrument, system operation, and data analysis procedures are described in detail. A CBR brightness temperature of 2.57 K with a 1 sigma uncertainty of + or - 0.12 K is obtained. The results are compared with measurements by other authors, and the cold-load antenna temperature and atmospheric model used in the study are discussed in appendices.
