\section{Analysis}  \subsection{Simple CO decomposition}  Many studies to date have found it necessary to decompose CO SLEDs into at least two components (cite some). One (cooler) component usually dominates in the lower-J CO lines while a warmer component dominates in the higher-J CO lines. Further work will do more involved modelling of the CO SLEDS for the BtP Galaxies, however, here we follow a very simple approach in order to estimate a first order cold/warm decomposition.  In order to estimate the cold component for our sample galaxies which have non-uniform J=1,2,3 coverage, we fix a MW template based upon the \citet{fixen99} data for the inner Milky Way. However, the J=1 line was suspect and we substitute the Amanogawa line for it. Furthermore, instead of using the raw data as a template, we fit a RADEX model in order to smooth out irregularities in the template SLED that are just due to meaurement error. We find a best-fit RADEX model to the MW SLED of x, x, x.  \subsection{CI and CO}
