Contour plots that show the difference between the temperatures of the model Z1 and the Z01 model (top panel) and the Z001 model (bottom panel). The right-hand column shows the difference in dust temperature and the left-hand column the difference in the gas temperature. The red color represents the regions where the model with lower metallicity has a higher temperature. The white and blue colors represent the regions where both temperatures are similar and where the Z1 model has a higher temperature, respectively.
