An important parameter to convert the observed temperatures into Mass is the excitation temperature.  \begin{equation} %\label{eqn:Mass from temp}  M(v, \alpha, \delta) = [H_2/^{12}CO] [{\rm H}_2/^{12}{\rm CO}]  \mu_m A(\alpha, \delta) F (T_{ex}) T_B(v, \alpha, \delta) \Delta v \end{equation}  Where
