Apply energy weight.
- Instead of using the Arb type histogram for sampling the energy spectrum,
energy is sampled by Linear distribution, and the Arb type histogram is
used for the weight of the generated particle.
- "/gps/ene/type LW" automatically applies this command.
- If this command has to be explicitly used, "/gps/ene/type" distribution mush be Lin.
Available at all Geant4 states.
