e_max

MCEq.config.e_max = 100000000000.0

The maximal energy is 1e12 GeV, but not all interaction models run at such high energies. If you are interested in lower energies, reduce this value for inclusive calculations to max. energy of interest + 4-5 orders of magnitude. For single primaries the maximal energy is directly limited by this value. Smaller grids speed up the initialization and integration.
