\section{\textsuperscript{12}CO compared to \textsuperscript{13}CO}  At present, all results are for \textsuperscript{13}CO. Attempts to analyse \textsuperscript{12}CO in the same way have failed to produce any significant results. It appears that \textsuperscript{12}CO is not optically thin. Once I have some solutions for \textsuperscript{12}CO, taking into account the fact that it is optically thick I will add those here.
