Table 4: Order-of-magnitude estimates of the values of the cross-section, $\langle\sigma v\rangle_0$, in units of ${\rm cm^3}\ {\rm s^{-1}}$, needed to reproduce the detected non-thermal emission features in Coma and to produce sizable signals for future indirect dark matter search experiments in the Milky Way.
