摘要

为了有效地应用射电天文方法测量大型天线增益，根据不同星表的数据，在考虑其角度尺寸和结构的情况下，分析了主要校准射电源（仙后座A和金牛座A超新星遗迹和射电星系天鹅座A）的通量密度差异问题。对下诺夫哥罗德研究所和其他射电天文台几十年来获得的关于这些射电源特征的数据进行了比较。

Data Analysis of the Characteristics of the Most Powerful Discrete Radio Sources Used in Gain Measurements of Large Antennas by Radio Astronomy

For the effective application of the radio astronomical method for measuring the gain of large antennas, the problems of discrepancies in the flux densities of the main calibration radio sources (remnants of supernova Cassiopeia A and Taurus A and the radio galaxy Cygnus A) have been analyzed according to data from different catalogues, as well as with allowance for their angular sizes and structure. The data on the characteristics of these radio sources obtained at the Nizhny Novgorod Research Institute and other radio astronomical observatories over several decades have been compared.
