 While we choose the position and momentum of all test-particles to be the same at the initial time, the masses are distributed according to the spectral function which depends on the initial momentum and position. We consider six different initial conditions:

 For the initial conditions 1-2 we expect that the nucleon propagates to its on-shell value of 0.938 GeV, while for the initial conditions 3-4 we expect just a less broad mass disribution of the test-particles at the end of the propagation. Finally, for initial conditions 5-6 we expect the spectral function to be the same after the propagation through the nucleus as the initial ones. The final results for each initial condition is shown in figures 1-6. The left plot shows the distribution of the test-particles as function of its mass and absolute position, i.e. the radius. And the right one shows just the distribution according to its mass. From those figures we conclude that our expectations are very well fulfilled and that besides some numerical noise the off-shell transport seems to work properly.
