Effects of the minimum electron Lorentz factor on particle and photon spectra of a nonthermal flare. Top panel: Electron distribution N_e(γ) multiplied by γ for different values of the initial Lorentz factor γ₀ and electron compactness ℓ_e (see inset legend). All other parameters are the same as in Table 1. Bottom panel: SSC spectra produced by the electron distributions shown on the left panel. The snapshots shown in both panels are computed at t = 11t_acc, 14.5t_acc, 17t_acc for γ₀ = 10^3.5, 10^2.7 and 10^0.7 respectively.
