Sky footprints of the surveys used in this work, shown in equatorial coordinates. Dots indicate the sky positions of cataloged sources in each survey: VLASS Epoch 2 (cyan), FIRST (purple), LoTSS Data Release 3 (DR3; khaki), and the HSC-SSP Wide-layer matched sample (black). The sources detected both in VLASS Epoch 2 and LoTSS DR3 are shown in green, reflecting the combined colors of the two surveys. The black outline highlights the approximate footprint of the HSC-SSP Wide layer.
