\caption{The column densities ($\times10^{13}~\rm  cm^{-2}$) of the C$_2\ X^1\Sigma^+_g\ (\nu\arcsec=0)$ rotational levels ($J\arcsec$).
The values written in boldface are derived from the (2--0)
band of the C$_2\ A^1\Pi_u\ -\ X^1\Sigma^+_g$ Phillips System. The values written in plain text were calculated from the Boltzmann distribution.\label{tab3}}
