Comparison of EW(Hα) and [OIII]/Hβ measurements derived from an aperture of 2 kpc and 3″ × 3″, respectively. Filled blue circles correspond to a comparison between measurements of EW(Hα) (right-hand plot) and [OШ]/Hβ ratio (left-hand plot) from our 2 kpc aperture (y-axis) and 3″ × 3″ aperture (x-axis). The measurements shown here correspond to the full MaNGA sample. The solid black line in both plots shows the one-to-one ratio that the values should follow if they have the same value.
