Determination of the Coordinates of Radio Sources on the Sun from RATAN-600 Observations in Multiazimuth Mode

Determination of the Coordinates of Radio Sources on the Sun from RATAN-600 Observations in Multiazimuth Mode

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 a...

description 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.
