Radio luminosity profile for R_projected = 0.75 Mpc and B = 2 μG. Solid black line shows the observed luminosity profile for relic RE at 1382 MHz, while the dashed black line represents the spectral index profile between 241 and 1382 MHz. The simulated intrinsic luminosity and spectral index profiles (i.e., without any projection effects), are shown in purple by solid and dashed lines, respectively. The simulated profiles, including the projection effects, are shown by solid lines for opening angles of 22°(cyan), 30°(green), and 40°(red). The corresponding spectral index profiles are shown by the dashed lines.
