Ratio δFSZ/F as a function of the synchrotron spectral index of the emitted spectrum of the radio halo, assuming a power law F(ν) ∝ ν− α and an average halo flux in a beam area at 330 MHz = 0.2 Jy. Calculations are reported at 1.4, 2.65, 4.85, and 8.45 GHz. Vertical dashed lines mark the synchrotron spectral index of the Coma radio halo derived from data at ν ≤ 1.4 GHz, α = 1.22 ± 0.04.
