Left: Resolved SFMS with two linear fits for high- and low-mass regimes respectively drawn as orange and purple solid lines. The hatched region corresponds to the range of values contributing both to the high- and low-mass ODR fits. The shaded area represents the scatter of the sole linear fit from the left panel of Fig. 7. Right: Resolved MGMS with the two linear predictions from the opposite SFMS fits represented by the dotted orange and purple lines for the high- and low-mass regimes. The dotted purple line is a prediction of the rMGMS at low surface densities, below the molecular-to-atomic phase transition. The shaded area represents the scatter of the sole linear fit from the right panel of Fig. 7. The rest of the legend in both panels is identical to the left and right-hand panels of Fig. 7.
