Reconstructed images of NGC 3191 from the MaNGA data cube. (a) SFR map. (b) Metallicity map in KK04 R₂₃ scale. (c) Dust-reddening distribution based on the Hα/Hβ Balmer decrement. (d) The [S III]/[S II] flux ratio, which is a proxy for ionization. In (c) and (d) only spaxels with S/N > 3 are shown. (e) Hα EW map. (f) [O III] EW map. The images are approximately 30 × 35 arcsec, corresponding to a physical size of about ﹩19\times 21\,\mathrm{kpc}﹩ at the redshift of NGC 3191. The effective spatial resolution is given by the PSF indicated in the lower left of each figure, which has FWHM of approximately 2.6 arcsec, or 1.6 kpc, and the physical scale is plotted in the bottom right corner.
