Abstract

The method (Kraus (2007)) for correcting atmospheric opacity in the C-band was applied to the RT-16 radio telescope of the Irbene observatory. The method is based on the calculation of the noise temperature T₀, which is almost independent of the environment and is determined by the characteristics of the receiver and radio telescope antenna. T₀ is determined using sky dip observations. The atmospheric opacity in the zenith is calculated using T₀. We have determined the time dependence of T₀ over a long period of time. It is shown that the T₀ error increases the error of the flux density by no more than 0.5%.
