Histograms of Σ(Hα) and EW(Hα). The HII-dominated spaxel values are shown in red, while DIG-dominated spaxel values are in blue. The dotted cyan lines indicate the classification by Lacerda et al. (2018), where DIG-dominated regions have EW(Hα) < 3 Å and HII region-dominated areas have EW(Hα) > 14 Å. The mean spaxel values of our DIG-dominated areas are indicated by the vertical black lines.
