rSFMS of one galaxy in our sample (NGC 4254) to illustrate the effect of removing Hα emission not associated with morphologically defined H II regions before resampling the SFR surface density map. Top: fiducial methodology. Bottom: alternative methodology as described in Sect. 5.4.1. The color scheme is the same as in Fig. 6. The black line correspond to the global rSFMS measured using all pixels with the fiducial approach (see Fig. 4).
