Local slopes s(p) and the distribution functions f_o(p)/n_o for the unmodified Sedov shock. The parameters are ${\overline{x}}_{\mathrm{pm}}=0.1$ (blue lines), ${\overline{x}}_{\mathrm{pm}}=0.05$ (red lines), α = 1 (solid lines), α = 1/3 (dashed lines), and p_max = 10⁴m_pc. The classic value (for u₂ = const) is s = 4 and is independent of p, α, and ${\overline{x}}_{\mathrm{pm}}$. Vertical lines: Left – energy of electrons for which the radio index is calculated in Fig. 6; right – protons with an energy of 240 GeV (see Sect. 5.2).
