Galaxy with a ring of the INT type radiation. Panel a: distribution of the spaxels with the SF-like (blue squares), intermediate spectra in the ring (red squares), and in the*1pt disc (orange squares), for the galaxy M-8249-12703. The circle marks the kinematical center of the galaxy. Panels b–e: variation with radius of the Hα line surface brightness Σ_Hα (panel b), the observed (non corrected fro the instrumental profile) gas velocity dispersionσ_gas, obs (panel c), X_BPT = log([N II]λ6584/Hα) (panel d), and Y_BPT = log([O III]λ5007/Hβ) (panel e). In each panel, 1 pixel corresponds to 0.276 kpc.
