Schematic illustration of the different energy regimes within a hotspot, with the low‐energy spectrum described by a region with index p = 2 (light gray), the high‐energy spectrum governed by a region with index p = 3 (dark gray) and the middle region described by a single power law with index p = p_m (white). The precise value of this index depends on how leaky the hotspot is deemed to be and the difference in dwell times in the hotspot of the particles that leak out most quickly and those which leak out most slowly.
