\caption{Test-particle: Magnetic field contrast factor,
$\sigma_{B}$, for a velocity ratio $v_{j}/v_{s}=10$, radius ratio
and self-similar thermal gas pressure ratio \citep[see][]{ch82}
and shock velocity, for different values of the indexes $n$ ($s=0$
and $q=0$). Nonlinear DSA: same as Test-particle but with lower
and upper limits on the magnetic field contrast factor,
$\sigma_{B}$, with $\eta_{{\rm inj}} = 10^{-3}$ (see Sect.
\ref{sect-Nonlinear-DSA} for more explanations).}
