21″ × 21″ cutout images for six sources in the cross-matched HSC, LoTSS Deep Field DR2 and ILT sub-arcsecond catalogues of ELAIS-N1. The LoTSS Deep Field DR2 images are restored with a circular Gaussian beam with an FWHM of 6″, and the ILT sub-arcsecond images are restored with a elliptical Gaussian beam with an FWHM of 0.36″ × 0.45″. For better visualisation, the minimum and maximum pixel value are fixed to [ − 1σ, 200σ], [ − 3σ, 130σ], and [ − 3σ, 10σ] for HSC, LoTSS, and ILT data, respectively, where σ represents the background RMS noise level for each image. The PSF sizes are shown in the bottom left corner of each panel. In the HSC and ILT panels, the bottom right corner shows the source position angles. For ILT sources, we also show the standard error of the position angle in a fan-shaped patch.
