T_e[N II] as a function of radius for all 19 galaxies. We compare individual H II regions (S/N > 3 open circles, S/N > 5 filled circles) with measurements from H II region stacks (squares and lines). Points are color-coded by their [N II] λ6583 Luminosity (L[[N II]]). Note: H II regions in NGC 4254 and NGC 4535 do not cover the full disk due to the AO notch filter. Galaxies are ordered from low (top-left) to high (bottom-right) stellar mass. All galaxies are shown with matched scales, so it is possible to directly compare the absolute values and slopes across the sample.
