LOFAR 50kpc-taper, discrete source-subtracted images of the RRs in the LoTSS DR2 - PSZ2 sample, from Botteon et al. (2022). The images and R500 (black circles) are centred on the PSZ2 coordinate. The image of PSZ2 G165.46+66.15 is centred on the X-ray centroid. PSZ2 G089.52+62.34, PSZ2 G091.79-27.00, and PSZ2 G165.46+66.15 have been re-imaged. A scalebar, denoting 1 Mpc, is shown in black. The beam is shown in the bottom-left corner, and the mass (M500, in units of 1014 M⊙), redshift (z), and image noise (rms, in units of mJy beam−1) are reported in the top-left corner. White crosses mark the location of the relics, as used throughout the paper (see Sec. 2.2 for a description of their calculation).
