Notes. For each object, we show α and report the values of the current lower limit on the volume-average magnetic field, BV, where available, and the detection sensitivity on the volume-average magnetic field, Bdt, for which IC emission would be detectable by ASTRO-H in 1 Ms. Additionally, is an optimistic estimate of the latter that corresponds to the intersection of the sensitivity curve and the thermal ICM emission, thus assuming the CXB is fully known and perfectly subtracted. The last two columns show the energy where non-thermal X-rays start to dominate the background for Bdt (), and the corresponding non-thermal flux density in units of in 10-12 erg cm-2 s-1, respectively. In the cases where γmin and/or γmin are calculated from the radio data and differ from the standard values that we adopt (see Sect. 3), we show them explicitly.

Thermal ICM emission computed using the model by Zandanel et al. (2014) for the gas density.
