Notes. We estimate the size (in arcmin2) of the halo in the sky in order to scale the ASTRO-H sensitivity correspondingly. In case of approximately spherical sources, this is conservatively estimated to be πDLLS/ 4, with DLLS the largest linear size. For elongated sources, this is approximated by a box (or ellipse) whose longest extent (or major axis) is DLLS. FX, UL is the current upper limit on the non-thermal hard X-ray flux in units of 10-12 erg cm-2 s-1, with ΔEX, UL the corresponding energy band. Γ is the literature spectral index used to derive FX, UL and then used to calculate the flux density for our analysis. The flux is defined as , where kx is a constant. The flux density is , with Γ the spectral index of the IC component. The ICM temperature, kT, in keV is also shown. The three columns of references are for the radio data, the non-thermal hard X-ray upper limit, and for the input parameters of the APEC model, respectively.
