Radial W₈₀ profiles for H₂ (top-left), [FeII] (top-right), [ArII] (bottom-left), and [ArIII] (bottom-right) for the five subsamples, as indicated by the different colours. These profiles are computed as median values of W₈₀ and distance of the spaxel from the position of the continuum peak, within circular rings of 250 pc width. The numbers next to each point indicate the number of galaxies used to compute it, and the shaded regions represent the range between the 25th and 75th percentiles of the W₈₀ values within each radial bin, illustrating the spread of values observed in each emission line.
