Slopes of the dust-total gas (left panel) and SFMS (right panel) SRs of sample galaxies individually evaluated at 3.4 kpc (see Sect. 5.2). Each colored dot corresponds to a galaxy. The transparent symbols represent the corresponding slopes at the resolution imposed by the dust map (see Sect. 5.1). The light blue band is the median slope with error and the gray star the slope of all galaxies at 3.4 kpc (see Table A.1). The total gas refers to the assumption of the constant X_CO (Bolatto et al. 2013).
