A robust preprocessing pipeline for RATAN-600 solar radio observations data

The RatanSunPy package was developed—an open-source Python software library designed to access, visualize, and analyze multiband radio observations of the Sun taken with the RATAN-600 solar complex. The package provides a full set of data processing tools including direct access to raw data, key preprocessing steps such as calibration to the quiet-Sun level, and tools for analyzing solar activity. These include automatic detection of local sources, matching them with NOAA (National Oceanic and Atmospheric Administration) active regions, and subsequent determination of the parameters of local sources and active regions. RatanSunPy enables more efficient exploration of the fine structure and dynamics of the solar atmosphere contributing to solar physics research and improving space weather forecasting. RatanSunPy is the first software package for processing solar observations from RATAN-600. The significance of the work lies in the fact that the RatanSunPy package will simplify access to and processing of RATAN-600 solar data potentially increasing research productivity and efficiency. RatanSunPy can be used, with appropriate adaptation, for processing solar radio observations from other telescopes.
