Upper panel: best fit for the SAURON data of NGC 474 (central kpc), from the pPXF procedure. The data is in black, the fit in red for the star component, and yellow for the gas component. The green points show the residuals and the pink line highlights the ionized gas component fit: from left to right, Hβ and the [OIII] doublet. Lower panel: weights of the different templates used by the regularized fit. Only colored regions are contained in the resulting fit. See text for details.
