Line ratio maps for various transitions of CO and ¹³CO for the dwarf galaxy. The line ratios are generally spatially uniform and show slight variation, unlike the disk galaxy. These maps are also patchy, especially for line ratios involving J = 3−2 and J = 4−3 transitions. This is due to the low number of SPH particles with densities close to 10⁴ cm^-3 which are a pre-requisites for these transitions. See caption of Fig. 7 for more details on interpreting the maps.
