Notes. The second column repeats the results from the detailed radiative transfer (RT) modelling, also given in Table 3. The following four columns give the 12CO/13CO line-intensity ratios corrected for antenna size for the different observed rotational transitions. The last column gives the average of the observed line-intensity ratios from Cols. 3–6.
