Test-particle distributions of the accelerated protons at the shock for the SNRs IC 443 (solid line) and W44 (dashed line). The parameters are n₁ = 120 cm⁻³, T₁ = 10² K, B₁ = 90 μG, x₀ = 1 pc, η = 0.5, d = 1.5 kpc with u₁ = 70 km s⁻¹ for IC 443; n₁ = 120 cm⁻³, T₁ = 10² K, B₁ = 10 μG, x₀ = 1 pc, η = 0.5, d = 2.9 kpc with u₁ = 35 km s⁻¹ for W44.
