Age, metallicity, and α-abundance profiles. Filled symbols are from the measurement of lick indices absorption line strengths with the measurement uncertainties on each point are shown. Open symbols are from the measurement of mass-weighted age and metallicity by full spectral fitting using pPXF, the error bars of which connect the maximum and minimum values measured from individual spaxels within each annulus. The vertical lines indicate the inner and outer boundaries of the star-forming ring.
