Results from the spatially resolved SED fitting for NGC 3312. Left panel: stellar mass surface density. Middle panel: observed g − i color index. Right panel: inferred internal dust reddening E(B − V). Not shown are the stellar population age map, showing consistently old ages throughout the entire face of the galaxy, with the exception of several very young regions coinciding with sites of active star formation where the youngest stellar population outshines the underlying, older generations.
