Table 2:

Constraints$^\dagger $ on the ratio of CR (non-thermal) to thermal energy ( $E_{\rm CR}/E_{\rm th}$) for the Coma cluster core region (within two radii) and assumed cosmic-ray distribution models A and B (see text).
Radius $\alpha$ Model $\eta = E_{\rm CR}/E_{\rm th}$ $E_{\rm CR}$ [erg]
0.2$^\circ $ (0.33 Mpc) 2.1 A <0.19 ${<}7.4\times 10^{61}$
0.4$^\circ $ (0.67 Mpc) 2.1 A <0.18 ${<}2.5\times 10^{62}$
0.4$^\circ $ (0.67 Mpc) 2.1 B <0.25 ${<}3.5\times 10^{62}$
0.4$^\circ $ (0.67 Mpc) 2.3 A <0.55 ${<}7.7\times 10^{62}$

$\dagger$ The upper limit for E>5 TeV has been used here.
