Table 2: Parameters of temperature profiles $T_{\rm e}(r)$ of our cluster sample. The estimated $\gamma $-ray flux $\mathcal{F}_{\gamma,~{\rm est}}~ ({>}\!100\mbox{ MeV})$ was calculated using the $\mathcal{F}_{\gamma}$-$F_{\rm X}$ scaling relation (Eq. (31)) with $\alpha _{\rm p}= 2.3$ and bolometric X-ray fluxes from David et al. (1993). Note that $\mathcal{F}_{\gamma}$ scales linearly with $X_{\rm CRp}$ which was set to $X_{\rm CRp} = 0.01~ X_{0.01}$ in this table. The range for $\mathcal{F}_{\gamma,~{\rm est}}$ reflects the temperature spread in cooling flow clusters between the central temperature T0 and the peripheral temperature T1.
