GandALF fits to the central (top panel) and outer aperture (bottom panel) spectra extracted from the MUSE data of FCC 167 (see Fig. 4). To allow a more direct comparison between these two spectra (black lines) and their respective GandALF fits (green and red lines), both data and models were normalised and rescaled. The residuals obtained by subtracting the model from the spectrum are also shown (bluepoints). These models used the entire MILES (Blasquez et al. 2006) stellar library as stellar templates to achieve the best possible fit. At the same time, to ensure a physically-motivated model only reddening by dust was used to adjust the templates to the observed shape of the stellar continuum. The position of the most prominent [O I] sky emission lines is indicated.
