Relations between SFR surface density and sSFRs and the second-over-first-component flux ratio. Black points represent Voronoi regions, where the point size is proportional to the inverse of the Voronoi covered area, so small points represent regions where more spaxels had to be binned to reach a satisfactory S/N. Strong blue lines represent a running median with a 20-point window, with weak blue lines representing the 1σ of the distribution.
