Age (upper panel) and metallicity (lower panel) as a function of radius along the major axis of IC 719. Blue points represent the primary component and red points the secondary component. In the lower panel, open squares mark the gas-phase metallicity measured by means of the [N II] λ6583 (green) and [N II] λ6583 + [O III] λ5007 (light green) emission lines.
