$^{a}$ See the text for the adopted column densities, Doppler widths, excitation temperatures and radiation field;
$^{b}$~\coc{12} band head position;
$^{c}$~total photodissociation rate in \ps{} at the edge and the centre, and the shielding factor at the centre;
$^{d}$~relative contribution per band to the overall photodissociation rate at the edge and the centre of the cloud;
$^{e}$~shielding factor per band: the absolute contribution at the centre divided by the absolute contribution at the edge.
