Coloured table of the column densities of neutral carbon (in cm⁻²) computed across shocks for different velocities and different strengths of the pre-shock magnetic field. The column densities are integrated in the direction perpendicular to the shock front over gas with a proton density, $n_{\mathrm{H}}⩽0.95n_{\mathrm{H}}^{\mathrm{f}}$. All other parameters are set to their standard values (see Table 2). Numbers in parenthesis are powers of ten.
