LoTSS DR2 144 MHz radio maps of giant DDRGs (sources 1 to 30 from Tab. A.1). The montage first presents newly discovered G-DDRGs, followed by previously known sources from the literature with different colour schemes. LoTSS colour maps and contours have angular resolutions of 6″ and 20″, respectively, displaying emission above 3σ. The RMS noise (σ) is typically ∼,80 μJy beam⁻¹, with each successive contour level increasing by a factor of $\sqrt{2}$.
