SZE brightness change ΔI/I is shown as a function of the observed radio spectral index α_r for the RG lobes in Table 1. The various panels refer to the cases p = 1,10,100,1000 from top down. Black triangles refer to SZE decrement at 150 GHz (in modulus) while the blue asterisks refer to the SZE increment at 500 GHz for p₁ = 1 and to the SZE decrement at 500 GHz (in modulus) for p₁ = 10, 100, and 1000. The SZE signals in Table 1 are all evaluated for a fixed value of the RG lobe magnetic field (B = 1 μG uniform in the emission region for all the objects considered).
