Fig. 2.
Example spectrum near the centre, 2.6″N, 0.4″E of the nucleus. Upper panel: an old metal-rich galaxy spectrum with a velocity dispersion of about 200 km s−1. The stellar population has been fitted with PyParadise, which enables us to subtract the stellar contribution and leave only the emission lines, which are shown in the lower panel. It is a LINER-like spectrum displaying the typical emission lines, which, in this case, are caused by the radiation field of post-AGB stars. The residual of the Mg b-band is only visible near the centre and is most probably caused by template mismatch.
