Scientific paper

The authors have measured the intensity of the cosmic microwave background radiation (CMBR) at a frequency of 1.410 GHz (21.26 cm wavelength), using a total-power radiometer. The brightness temperature of the CMBR at 1.410 GHz is 2.11±0.38K at the 68% confidence level. The predominant sources of error are uncertainties in the reflection characteristics of the absolute reference load (0.03±0.31K), subtraction of the signal from the galaxy (0.80±0.16K), and Earth's atmosphere (0.83±0.10K).
