Abstract:
Search for deviations from a Planck distribution in the spectrum of the Cosmic Microwave Background at frequencies close to 1 GHz Minimum/Maximum Altitude: 2900m
Quality
The absolute temperature of the sky is obtained by difference looking alternatively to the sky and at a well known artificial blackbody at liquid helium temperature. Then the ground, atmospheric and galactic signal are subtracted. Observations at 0.82 and 2.5 GHz.
