Radial profiles of the stellar mass (left), molecular gas mass (middle), and SFR (right) surface densities of BX610, plotted with the same logarithmic dynamic range to facilitate comparison. Colors indicate the same as in Figure 2. In the right panel, green squares above the gray-shaded area are derived from the rest-frame 630 μm dust continuum emission, while black squares outside the area are derived from Hα corrected by dust attenuation profile of Tacchella et al. (2018). We also indicate for comparison the Σ_SFR(Hα) data in the central region as black-filled squares, but with a dashed line. The vertical gray dotted line indicates the beam radius. We observe in the central region of the right panel that the SFR_Hα surface density is clearly underestimated in comparison with the SFR_dust surface density.
