Comparison of the observed ¹²CO emission lines (black histogram), and the line profiles predicted by the GASTRoNOoM-model (red dashed line) with parameters as listed in Table 5. The line transitions J − (J − 1) and the telescopes with which they were observed are indicated in the upper left corner of every panel. The factor I_MB,model/I_MB,data is given in the upper right corner of every panel.
