Comparison between observations and model results for the species not presented in the main text. The data pointsrepresent the observations (traditional dense gas tracers in blue and additional tracers in green), and the red dashed lines represent the model results. Each panel row contains all observed transitions and isotopologs of any given molecular species, except for the last row that shows together the only observed lines of CN and C₃ H₂. Several SO and C₃H₂ points can be seen above the plot lower limit at very low column densities. A visual inspection of their spectra suggests that they represent noise or baseline residuals, and not true molecular emission.
