Schematic overview of the data-processing workflow in this work. After splitting the 2C data into three antenna spectra, we first conduct a general comb diagnostics for each antenna, then perform per-antenna PCA decomposition, basis alignment, and periodogram/FT/ACF analysis. The component-level results are finally combined to distinguish non-shared periodic signals from shared or comb-like RFI. -- astro-ph.IM

Chang’E-4 (CE4), the first mission to soft-land on the lunar farside, provides a unique opportunity for astronomical observations from an environment shielded from terrestrial radio interference, and thus serves as […]
