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. The maps obtained using our fiducial set of templates are shown in the left column. The area outside the red ellipse in the top-left panel is used to probe disk stellar population properties, and the area between the red and the black ellipses is used to probe stellar population properties of the young star-forming ring (see text).
