Table 7:

Results of the gamma-ray emissivity analysis of the LMC for hypotheses $\mathcal{H}_1$ and $\mathcal{H}_2$ .
Parameter	$\mathcal{H}_1$	$\mathcal{H}_2$
$\Phi_{\gamma}$	$25.0\pm1.7\pm4.1$	$15.2\pm1.9\pm3.4$
$q_{\gamma}$	$6.9 \pm 2.4 \pm 2.6$	$4.2 \pm 1.5 \pm 1.7$
$r_{\rm c}$	$0.31 \pm 0.01 \pm 0.02~^{+0.13}_{-0.07}$	$0.21 \pm 0.01 \pm 0.02~^{+0.09}_{-0.05}$

Notes. Given are the integrated >100 MeV photon flux $\Phi_{\gamma}$ in units of 10^-8 ph cm^-2< s^-1, the average >100 MeV gamma-ray emissivity $q_{\gamma}$ in units of 10^-27 ph s^-1 sr^-1 H-atom^-1, and the cosmic-ray enhancement factor $r_{\rm c}$ . Quoted errors are statistic and systematic. For $r_{\rm c}$ we quote in addition the (asymmetric) systematic error related to the uncertainty in the total LMC gas mass.
