ICS flux predicted for the 21 RG lobes in Table 1 in the SXR, HXR, and gamma-ray bands is compared to the instrumental sensitivity of Swift-XRT, Swift-BAT, and Fermi-LAT. Open dot mark the RG lobes with F_ICS(1   GeV) larger than the Fermi-LAT sensitivity. The black diamonds mark the seven RGs for which we perform a detailed study. We plot the gamma-ray flux at 1 GeV and the X-ray flux at the centers of the 2−10 keV and 20−80 keV energy bands. The SZE flux is calculated at 150 GHz.
