Radio halo and relic spectrum. Flux density measurements from this work, Clarke & Enßlin (2006), Brentjens (2008), and Intema (2009) were included. The solid straight line is a power-law fit to the relic fluxes. The radio halo spectrum is from flux density measurements summed over the region indicated in Fig. 7.
