\caption{Results for line current runs as functions of the curvature radius of the field line used, shock speed~$V_{\rm s}$ and compression ratio~{\em r}. Shown are the relative amount of HEP~escaping to the downstream region~(ds), maximum energy reached $E_{\rm max}$ (in~$\log{}_{10}({\rm eV})$) and the spectral index~$\sigma$ with error limits, ${\rm d}N/{\rm d}E \propto E^{\sigma }$. In this setup there are no particles escaping to the upstream region.}
