Coloured table of the FWHM (in km s⁻¹) of the absorption lines originating from the ³P₂ level of neutral carbon computed across shocks for different velocities and different strengths of the pre-shock magnetic field. The FWHMs are obtained by fitting Gaussian profiles on the velocity profiles predicted by the shock model in the direction perpendicular to the shock front taking only into account 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).
