\caption{\label{tab:ch2cn.dib.pars}Least-squares fit parameters of the \dib8037 CH$_2$CN$^-$\ models shown in Fig.~\ref{fig:ch2cn.fits}. The mean LSR velocity ($v_{\rm LSR}$~/~km~s$^{-1}$), Doppler cloud width ($b$/km~s$^{-1}$) and equivalent width of the model \dib8037 DIB ($W_{8037}$/m\AA) are given along with the normalised continuum rms of the observed spectra ($\sigma_{\rm c}$), and the rms of the model fit residuals ($\sigma_{\rm f}$).}
