Radial disributions of the sufrace brightness in the Hα and oxygen [O III]λ5007 emission lines and D_n(4000) index in the MaNGA galaxy M-8454-12702. Panel a: Surface brightness Σ_Hα as a function of radius. The blue symbols denote the spaxels with the H II region-like spectra, dark symbols mark the spaxels with the AGN-like spectra, and the red symbols are the spaxels with the intermediate spectra. The golden dashed line shows the median value Σ_{Hα, median} of the surface brightness in the spaxels with the optical radius of the galaxy. Panel b: Same as panel (a) but for the oxygen [O III]λ5007 emission line. Panel c: D_n(4000) index as a function of radius. The grey points denote D_n(4000) indeces in the individual spaxels, red circles mark the median values of the D_n(4000) in bins of 0.05 in the fractional radius R/R₂₅, bars show the scatter in the D_n(4000) about the median value in the bins, and the blue dashed line shows the median value of the D_n(4000) in all the spaxels within optical radius.
