Luminosity-weighted age (top row), luminosity-weighted [Z/H] (middle row), and stellar E(B-V) (bottom row) maps derived for the central star-forming ring of NGC 3351, once the stellar continuum has been removed from the observed spectra and the templates. Each column shows the maps obtained using the set of templates indicated at the top of each column. The maps obtained using our fiducial set of templates (after removing the stellar continuum) are shown in the left column. We note that the E(B-V) maps are identical to those in Fig. E.2, as the stellar extinction is measured before subtracting the stellar continuum.
