摘要

Kraus(2007)校正c波段大气不透明度的方法应用于Irbene天文台的RT-16射电望远镜。该方法基于噪声温度T0的计算，噪声温度T0几乎与环境无关，由接收机和射电望远镜天线的特性决定。T0是通过天空倾角观测确定的。使用T0计算天顶的大气不透明度。我们已经确定了T0在很长一段时间内的时间依赖性。结果表明，T0误差对磁通密度误差的影响不超过0.5%。

Atmospheric opacity correction in C-band at Irbene RT-16 radio telescope

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%.
