Temporal evolution of the integrated energy of energetic leptons $E_{\text{total}}^{\text{CR}}$ within the total computational domain for several bins of particle energy as indicated in the plot. We show the results for the second (left) and third (right) orbit of our simulation. Relevant orbital phases are indicated in the plot via vertical lines, where additionally periastron is at φ = 0. The error bars indicate the short-time variation in the six phases used to compute each data point.
