Maps of the simulated relic. Top left: radio power at 1.4 GHz. Top right: spectral index measured between 4.85 GHz and 140 MHz. Bottom left: polarised radio power at 1.4 GHz overplotted with the magnetic field angle (B vectors). Bottom right: polarisation fraction at 1.4 GHz. In each map, the resolution is (12.6292 kpc)² per pixel, which corresponds to 13.5″ at the distance of Abell 3667. Each map was smoothed with a Gaussian of size σ = 27″.
