SFR and Σ_SFR versus galactocentric distance (top), and mass and Σ_mass versus galactocentric distance (bottom). Filled circles are centered and lopsided knots and open circles represent offcenter knots. The distribution of each quantity in the y-axis is shown at the right of each panel, solid line is for centered and lopsided knots, and dotted line is for offcenter knots. As can be seen, the most massive and high star-forming regions are in the central part of the host galaxies. For the sake of clarity, Sknots have not been displayed.
