Luminosity-weighted age (top row), luminosity-weighted [Z/H] (second row), stellar E(B-V) (third row), and stellar mass surface density (bottom row) maps derived for the central star-forming ring of NGC 3351. Each column shows the maps obtained using the set of templates indicated at the top of each column, accounting for nebular continuum emission using the approach Neb. B (see main text). The maps obtained using our fiducial set of templates (with the modifications described) are shown in the left column.
