Profiles of the photon count, normalized to the respective maximum. Here we show the example of impulsive (top) and continuous (bottom) acceleration, D₁₀ = 10²⁶ cm² s^-1, at an accelerator age of, from bottom to top, 10³ (red), 10⁴ years (green), and 10⁵ years (blue). Error bars are set to 10% of the count number, to mimic the expected error on the effective area for the array used in the counts determination.
