Top: Metallicity map (on the left) and metallicity gradient (on the right) of the galaxy ’JO206’ (z = 0.051, logM_*/M_⊙ = 10.96). Bottom: Spatially resolved map of the luminosity of the [O III]λ5007 line (on the left) and ionization parameter log(U) (on the right). The red circle encloses the aperture with a (non-de projected) radius of ∼ 1 kpc, within which the median values of logL[O III] and logU have been computed; this is also noted. These values are also noted on top of the plots (e.g., logL[O III]_{r <  1kpc} and logU_{r <  1kpc}).
