Abstract

We provide an analytical description of the method for the determination of the coordinates of solar radio sources from multi-azimuth observations on RATAN-600. We analyze models of the displacement of the object across the scan depending as a function of azimuth taking into account solar rotation and suggest a method for estimating the rate of displacement due to rotation. We demonstrate the results of the application of the method using the determination of the coordinates of a radio source in the active region NOAA 11 520 as example. After eliminating gross scan referencing errors we obtained the coordinates, which agree well with observational data. We discuss the scan coordinate reference errors.

从多方位角模式下的RATAN-600观测值确定太阳上的无线电源坐标

摘要

我们提供了从RATAN-600的多方位观测确定太阳无线电源坐标的方法的分析说明。我们在考虑到太阳旋转的情况下，根据方位角的函数分析了整个扫描过程中对象位移的模型，并提出了一种估计由于旋转而引起的位移速率的方法。我们以确定活动区域NOAA 11 520中无线电源的坐标为例，演示了该方法的应用结果。消除总扫描参考误差后，我们获得了与观测数据非常吻合的坐标。我们讨论了扫描坐标参考误差。
