Example of a SSP fitting for a simple spaxel of the galaxy NGC 863. The observed, rest-framed and resampled spectrum is coloured in green. The black spectrum is the best fit synthetic spectrum we get from the STARLIGHT SSP fitting, and the blue spectrum is the nebular emission of the spaxel, obtained from the residue of the fit, subtracting the synthetic spectrum to the observed.
